Market square jewellery store, Mappin and Webb was left reeling after it was raided in broad daylight.
At 3.31 on Tuesday afternoon, onlookers claim that three men smashed a window and made off with jewellery before running towards King’s Parade and away down Trumpington Street.
The men have been described as between 18 and 19, black, and wearing hooded tops. One of the men was wearing top with a greay and black design. No weapon was thought to have been used.
The incident marks the third raid on the store in only a matter of months. In September, three men armed with a handgun used hammers to smash glass cabinets.
This followed a robbery in July, where three men, armed with a claw hammer and a gun made off with Rolex watches and jewellery worth around £140,000;.
The police said that they were investigating the incident that took place in July as part of a series of high-value jewellery thefts around the country.
