What is transit remand?

When a warrant of arrest is executed outside the district in which it was issued, the person arrested shall, unless the court which issued the warrant is within thirty kilometers of the place of arrest or is nearer than the Executive Magistrate or District Superintendent of Police or Commissioner of Police within the local limits of whose jurisdiction the arrest was made, or unless security is taken under section 71, be taken before such Magistrate or District Superintendent or Commissioner.
