However, before they can do this, they must have a good reason and tell you why they are searching you.
Police officers don't have to be in uniform but if they're not they must show you their warrant card.
Being able to do this helps to keep the public safe, tackle crime, anti-social behaviour and prevent terrorism.
If you are stopped and searched it does not mean you are under arrest or have done anything wrong and does not automatically mean you will have a police record.

The feedback you provide is presented at our Stop and Search Scrutiny Panel, considered in future training practices and processes and fed back directly to officers.
We will respond accordingly to responses provided to us via the survey. If you wish to contact us directly to discuss Stop and Search please email firstname.lastname@example.org
