Undercover in Britain's bookies
New figures seen by BBC Panorama show there has been a rise in violent crime in betting shops since the introduction of the Gambling Act five years ago.
Police statistics obtained under Freedom of Information show violent crime in betting shops in Britain rose by 9% between 2008 and 2011.
Betting shop managers told the programme they believed one cause was high stake, fast-paced gaming terminals.
Presented by Sophie Raworth, Panorama went undercover to test those claims.
