Thieves broke into a Greater Manchester branch of John Lewis on Sunday night and stole up to £40,000-worth of watches and jewellery.
According to a report in the Manchester Evening News, thieves forced open the shutters of the Cheadle Royal store at 8.40pm on Sunday night and made of with watches and jewellery believed to be worth a total of between £30,000 and £40,000.
Stockport West Neighbourhood Police, part of Greater Manchester Police, said they believed the items could be offered for sale in the run up to Christmas. Police are appealing for witnesses to the crime.
Inspector Dave Barrett said: "It is a significant theft in the run up to Christmas with a substantial amount stolen, which is now out in the public domain and needs to be offloaded.
"Anyone offered any goods for sale at knock-down prices should be concerned where it has come from and should let us know. If it seems too good to be true it probably is."
Anyone with information that could help the police should call 101.
