Armed robbers burst into Asda superstore in Biggleswade on Saturday night and threatened staff.
The incident happened at 10pm on Saturday, January 4 as staff were cashing up the day’s takings at the Church Street supermarket.
Four masked men entered the store armed with what is believed to be copper pipes designed to look like firearms.
They threatened staff and assaulted a security guard, who suffered minor injuries, before leaving with a substantial amount of money.
The offenders left in a dark blue Audi A4 on false ’52 number plates, which was being driven by a fifth offender.
They left in an unknown direction and later abandoned the vehicle which has since been recovered.
