Cardboard Citizens is a theatre group made up of actors who were once homeless or in prison.

The group is touring the country in an effort to intervene in the lives of offenders leaving jail.

Errol McGlashan was a repeat offender for 30 years.

He spoke to BBC News about how theatre helped to keep him out of prison.
