Risk of radicalisation of Muslim inmates in UK prisons

The head of the prison and probation service for England and Wales says there is a 'significant risk' of Muslim inmates becoming radicalised.

Michael Spurr has told BBC Panorama that while the risk is small, radicalisation in prisons needs to be combated.

Panorama's Raphael Rowe followed one convict released from prison into the arms of Islamic extremists.
