to assist him/her in the execution of their duties in relation to a particular incident, investigation or operation, a BTP constable also has the powers of the requesting officer for the purposes of that incident, investigation or operation. If a constable from a territorial police force makes the request, then the powers of the BTP constable extend only to the requesting constable's police area. If a constable from the MDP or CNC makes the request, then the powers of the BTP officer are the same as those of the requesting constable.
