Detectives have released CCTV footage of the moment four masked men smashed their way into a jewellery shop in Ely.
Police were called at about 2.50am on Friday morning (13 November) to reports of a break in at The Italian Jewellers in High Street Passage.
The thieves ransacked the store before making off with more than £100,000 worth of rings and watches.
Detective Sergeant Ashley Ryan, who is investigating, said: “This was a smash and grab which saw a staggering amount of jewellery stolen in a matter of minutes.
“I’m urging anybody who has any information about the incident, or who recognises the men, to get in touch as a matter of urgency.”
