A man threatened staff at a supermarket in St Neots with a knife during an attempted robbery.
Police have released a CCTV image of a man they would like to speak to in connection with the incident, which took place at Tesco, in Barford Road, at around 4pm on August 29.
According to officers, a fire alarm was activated and the store was evacuated.
As customers returned, a man was stopped by security for attempting to steal £308 of alcohol.
He tried to flee, throwing the stolen goods at staff before threatening them with a large kitchen knife. Staff later managed to recover £208 worth of stolen items.
The man was seen leaving in a blue Vauxhall Astra.
DC Martin Hardy said: “I would urge anyone who was in Tesco this day or that may know the man pictured to come forward.”
