Three men with sledgehammers smashed their way into the Asda superstore in Kings Hill on Saturday night.

Staff were threatened by the balaclava wearing robbers who broke through a firedoor to enter the supermaket at 9.30pm.

They grabbed a cash trolley and made off with an as yet undisclosed sum of money.

Police carried out a forensic examination of the store following the incident and are viewing CCTV footage from the area as part of their ongoing investigation.
