A CCTV image of a man has been released following a botched raid at a bookmakers in north Watford.
Hertfordshire Constabulary said a man went into Ansells Bookmakers, in St Albans Road, at around 4.20pm.
Police said when a cashier turned her back the man climbed over the counter and tried to snatch money from the till.
The cashier then managed to secure the money before being pushed by the man who made off with the till drawer.
Police said the suspect ran off towards the town centre.
Anyone who recognises the man pictured or has information about the incident is asked to contact Hertfordshire Constabulary on its non-emergency number 101 quoting crime reference number C4/14/362.
