What type of warrant is required to extend the investigation period?

To extend the investigation period effectively, a detention warrant is required. This type of warrant allows law enforcement to detain a suspect for a longer duration beyond the initial legal limits, typically associated with an ongoing investigation. When law enforcement agencies need additional time to collect evidence or clarify the circumstances surrounding a case, obtaining a detention warrant ensures that the detention aligns with legal standards and protects the rights of the individual involved.

A judicial warrant is generally issued by a judge and is required in various circumstances, including arrests and searches, but it does not specifically address the need to extend investigation periods. A search warrant is needed to conduct searches of premises or seize property but does not pertain to detaining individuals for an investigative timeframe. An arrest warrant is focused on formally apprehending a suspect for a specific crime and does not cater to extending an investigative timeframe.

In this context, the detention warrant addresses the necessity of prolonging the investigative process legally, thereby justifying the correct answer.
