Important Differences Between Detention and Arrest

Detention

Detention is the act of holding a person in a police station or other place of custody for a short period of time. It is a temporary measure taken by law enforcement during an investigation of a suspected crime, to prevent a person from fleeing, or to protect the safety of others. The length of detention can vary depending on the circumstances and the laws of the jurisdiction, and a person may be held without charge for a certain period of time. It’s important to note that detention is different from arrest, as an arrest typically involves formal charges and the beginning of a criminal case.

Examples of Detention

Examples of detention include:

  • A suspect being taken into custody and held in a police station for questioning about a crime they are suspected of committing.
  • A person who is seen acting suspiciously and is held temporarily in a police station until their identity can be verified and any potential danger to others can be assessed.
  • An individual who is considered to be a threat to national security and is taken into custody and held for a period of time for further investigation.
  • A migrant who is caught crossing the border illegally and is taken into custody until they can be processed and either released or deported.
  • A person who is arrested for a crime and held in jail until they can be arraigned in court.

Types of Detention

There are various types of detention, including:

  1. Police custody: A person is taken into police custody for questioning about a crime they are suspected of committing, or for their own protection.
  2. Immigration detention: An individual who is considered to be in the country illegally may be taken into immigration detention.
  3. Pre-trial detention: A person who has been charged with a crime may be held in pre-trial detention if they are considered a flight risk or a danger to the community.
  4. Administrative detention: An individual may be taken into administrative detention if they are considered to pose a threat to national security or public safety, without being charged with a specific crime.
  5. Juvenile detention: Juveniles who have been charged with a crime may be held in a juvenile detention center.
  6. Psychiatric detention: A person who is deemed to be a danger to themselves or others due to a mental health condition may be taken into psychiatric detention for evaluation and treatment.

Process of Detention

The process of detention varies depending on the jurisdiction and the specific circumstances, but generally involves the following steps:

Step 1. Detention by law enforcement: A person is taken into custody by a law enforcement officer. This can happen after an arrest, or as a result of a temporary detention for questioning or to prevent a person from fleeing.

Step 2. Processing: The person is processed, which may include being searched, having their personal belongings confiscated, and being fingerprinted and photographed.

Step 3. Booking: The person is booked into a police station or jail, and their personal information is recorded.

Step 4. Initial hearing: Depending on the jurisdiction and the type of detention, the person may be required to attend an initial hearing or arraignment, where they are informed of the charges against them and their rights.

Step 5. Detention review: A person who is being held in detention may be entitled to periodic reviews of their detention, to ensure that it is still necessary and lawful.

Step 6. Release: A person may be released from detention if the investigation is complete, if they are no longer considered a flight risk or danger to others, or if they are granted bail.

Purpose of Detention

The purpose of detention can vary depending on the specific circumstances, but it generally serves one or more of the following purposes:

  • Investigating a suspected crime: A person may be taken into detention in order to question them about a crime they are suspected of committing.
  • Preventing a person from fleeing: A person may be taken into detention if they are considered a flight risk, in order to prevent them from leaving the jurisdiction and avoiding prosecution.
  • Protecting the safety of others: A person may be taken into detention if they are considered a danger to the safety of others, in order to prevent them from causing harm.
  • Gathering evidence: A person may be taken into detention in order to gather evidence related to a crime, such as through a search of their property or questioning of witnesses.
  • Ensuring compliance with immigration laws: An individual who is considered to be in the country illegally may be taken into immigration detention in order to ensure compliance with immigration laws.

Arrest

An arrest is the act of taking a person into custody by a law enforcement officer, with the intention of charging them with a crime. The purpose of an arrest is to bring a suspect before a court to answer criminal charges, and it marks the beginning of a criminal case. An arrest can be made by a police officer with a warrant, which is a court order authorizing the arrest, or without a warrant if the officer has probable cause to believe that a crime has been committed.

After an arrest, a person may be held in jail, released on bail, or released on their own recognizance (a promise to appear in court). The specific conditions of release and the process for an arrest vary depending on the jurisdiction and the circumstances of the case. It’s important to note that a person who has been arrested has certain rights, including the right to remain silent, the right to an attorney, and the right to a fair and impartial trial.

Examples of Arrest

Examples of arrests can include:

  • Arrest for a violent crime: A person who is suspected of committing a violent crime, such as assault or robbery, may be arrested by a police officer.
  • Arrest for a drug offense: A person who is suspected of possessing or selling illegal drugs may be arrested by a police officer.
  • Arrest for DUI: A person who is suspected of driving under the influence of alcohol or drugs may be arrested by a police officer.
  • Arrest for theft: A person who is suspected of stealing property may be arrested by a police officer.
  • Arrest for a white-collar crime: A person who is suspected of committing a white-collar crime, such as embezzlement or fraud, may be arrested by a police officer.
  • Arrest for a traffic violation: A person who is suspected of violating traffic laws, such as speeding or running a red light, may be arrested by a police officer.

Types of Arrest

There are several types of arrests, including:

  1. Warrant arrest: An arrest made with a warrant, which is a court order authorizing the arrest of a person. A warrant is typically issued if a law enforcement officer has probable cause to believe that a person has committed a crime.
  2. Warrantless arrest: An arrest made without a warrant, typically in cases where a law enforcement officer has probable cause to believe that a crime has been committed and the person is in immediate danger of flight or escape.
  3. Consent arrest: An arrest made with the voluntary cooperation of the person being arrested.
  4. Felony arrest: An arrest for a serious crime, such as robbery or murder, that is punishable by a prison sentence of more than one year.
  5. Misdemeanour arrest: An arrest for a less serious crime, such as disorderly conduct or petty theft, that is punishable by a fine or imprisonment for less than one year.

Process of Arrest

The process of arrest can vary depending on the jurisdiction and the specific circumstances, but it generally includes the following steps:

Step 1. Probable cause: A law enforcement officer must have probable cause, which is a reasonable belief based on facts and circumstances, that a crime has been committed and that the person being arrested committed the crime.

Step 2. Verbal or physical restraint: The law enforcement officer must physically take the person into custody, or the person must agree to accompany the officer voluntarily.

Step 3. Notification of rights: The person being arrested must be informed of their rights, including the right to remain silent, the right to an attorney, and the right to a fair and impartial trial.

Step 4. Booking and processing: The person being arrested must be booked into a jail or detention center, and their personal information, such as their name and address, must be recorded.

Step 5. Bail and release: The person being arrested may be released on bail, which is a sum of money paid as a guarantee that the person will appear in court, or may be released on their own recognizance (a promise to appear in court).

Step 6. Arraignment: The person being arrested must appear in court for an arraignment, which is a formal reading of the charges against them.

Purpose of Arrest

The purpose of an arrest is to take a person into custody with the intention of charging them with a crime and bringing them before a court to answer criminal charges. An arrest marks the beginning of a criminal case and serves several important functions:

  • To protect the public: An arrest is often necessary to protect the public from a person who is suspected of committing a crime and is believed to pose a danger to others.
  • To secure evidence: An arrest can be used to secure evidence that may be needed for a criminal trial, such as physical evidence or a confession.
  • To prevent flight or escape: An arrest can be used to prevent a person from fleeing or escaping, which would impede the administration of justice.
  • To bring the accused before a court: An arrest is a step in the process of bringing the accused before a court to answer criminal charges, which is an important part of the criminal justice system.
