What does intrastate detainer mean?

An intrastate detainer refers to a legal request or hold placed on an individual who is already in custody within the same state, typically due to pending charges or warrants from a different jurisdiction within that state. This allows law enforcement or correctional facilities to maintain custody of the individual for additional legal proceedings without releasing them. Intrastate detainers are often used to streamline the process of addressing multiple legal issues that a person may face simultaneously.
