People who are stopped and searched by police in Greater Manchester are being told of their rights.
A new code of practice tightening up the rules around stop and search was introduced in April.
The Greater Manchester Police Authority is launching a new campaign on Tuesday to raise awareness of the changes.
Chief Constable Michael Todd says the searches can help police detect crime.
But he says officers can only search someone if they suspect them of carrying drugs, weapons, stolen property or items that could be used to commit a crime.
The officer must tell the person what law is being used and their rights, the officer's name, the station they work at and why they stopped the person.
The officer must also say what they are looking for.
The police authority says it aims to improve the trust and confidence in the police.
