Mental health pilot: My experience with the police

4 January 2014 Last updated at 12:27 GMT

Mental health nurses will be based in police stations and courts in 10 areas of England as part of a pilot scheme aimed at cutting reoffending.

The nurses' duties will include helping officers to respond to calls and identify those with problems.

Roger has a long history of trouble with his mental health and the police, who he says do not have the training to deal with him.
