Section 55: Orders for Arrest by a Subordinate
If a police officer wants someone else in the police force to make an arrest, they must give that officer a written order. The order must say who to arrest and why.
The officer making the arrest must tell the person being arrested about the order and show it to them if they ask.
This rule doesn't stop a police officer from making an arrest without an order if they are allowed to do so by law.
