The moment masked robbers burst into Selfridges and smash the display cabinets Jaeger le Coultre, Hublot and Cartier watches were also stolen in the raid which took place on the ground floor of the five storey building at 7.20pm on Wednesday as wealthy customers were browsing for jewellery . The gang escaped in a Black Mercedes Benz driven by a fourth man. The car was found abandoned half a mile away near Manchester prison - formerly Strangeways. Greater Manchester Police said the men were wearing high visibility jackets and trousers. It is believed the raid took place after the store had a reshuffle of its departments. Det Con Adam Cronshaw said: "This was a brazen robbery while the store was open and busy with members of the public. It was clearly well planned and executed. These men were in and out in less than 80 seconds and were very particular about the watches they selected. I am appealing for anyone who knows who is responsible or has overhead someone talking about this robbery - either before or after it happened - to contact us in absolute confidence. The clothing worn appears to be brand new and I am also eager to hear from anyone who knows where they may have been purchased or manufactured. The offenders will, at some point, undoubtedly look to off load these watches and I would urge people to be mindful of this robbery and again if anyone is approached with a view to buying any of these items to please contact us. A spokesperson for Selfridges said: "A robbery took place at our Manchester Exchange Square store on Wednesday, 19 September, just before 7.30pm. The police are currently investigating and we are helping them with their enquiries.
