About third of those arrested in England have mental health issues. The BBC met the nurses who help them.
An estimated third of those arrested by police in England are experiencing mental health problems.

Most police forces now have mental health nurses working with them to help those arriving in crisis, in the hope of both improving their health and reducing re-offending.

The BBC's Jeremy Cooke was given exclusive access to see the process in action at the Nottinghamshire Police central custody cells.
