A police force no longer makes suspects wear boiler suits while their clothes are being tested in case it infringes their human rights.
Officers from Greater Manchester Police have been told not to make detainees wear blue paper boiler suits. Instead, under rules brought in earlier this year, they must be given the opportunity to wear their own clothes while they await questioning.
If a relative of the suspect cannot bring an outfit, an officer can be sent to their house to pick up a fresh change of clothes, or a white tracksuit can be issued.
A spokesman for Greater Manchester Police said: "The blue boiler suits are no longer used by the force and, where possible, arrangements will be made to collect clothes from the homes of suspects.
"This may be family members bringing them in or they may be collected. We are also able to issue white tracksuits. The force is following best practice guidelines."
Under the Police and Criminal Evidence Act 1984 all suspects have to be dealt with quickly, fairly and "without oppression" while in custody.
However, individual forces are free to introduce their own best practice rules of procedure, the spokesman added.
