A cross-dressing robber was part of an armed gang who targeted a shop in Bury.
At 4.15pm on Wednesday 5 May 2010, a man, dressed as a woman in a burka and hijab, was allowed entry into Capri Jewellers on Benson Street.
As soon as he was buzzed in a further three men, one of whom had a shotgun, barged in.
The group stole a large amount of jewellery, including bangles, rings and lockets, before escaping in a waiting car, thought to be a silver Toyota Yaris, towards Alfred Street.
The offender dressed as a woman is described as Asian, over 6ft tall and of thin build.
The getaway driver is described as Asian, in his early 20s, of chubby build. He was bald and wearing glasses.
The other three offenders are described as Asian and were wearing balaclavas.
The gang left behind two canvass holdalls that were branded 'Wei Bao'.
Detective Constable Chris Jameson, of Bury CID, said: "The store has very tight security so the ruse used to gain entry shows a level of detailed planning and I want to hear from anyone who may
have overheard the gang preparing for this robbery.
"I would also urge anyone who knows the whereabouts of the getaway car or who may have been approached with a view to buying the stolen items to call police.
"All information will be treated in strict confidence."
Anyone with information is asked to call Bury CID on 0161 856 8248, or the independent charity Crimestoppers, anonymously, on 0800 555 111.
