MASKED raiders stole £20,000 of jewellery from a pawn brokers in Leigh.
Three men entered Harvey and Thompson Pawnbrokers on Bradshawgate armed with hammers and threatened staff.
Two of the men forced staff to open the door to the window display containing jewellery. The third man threatened other staff members to open the cash register during the incident which happened at around 5pm on Thursday December 15.
The gang stashed the gold and silver jewellery and cash into a brown-coloured duvet cover.
All three got into a stolen pale blue-coloured Golf and drove off. This car was later found burnt out and it is believed the offenders switched to a stolen red Mini.
The thieves used a concrete slab to smash their way through the window of the Standish property before stealing the cars.
No-one was injured in either incident.
Police are now appealing to anyone with information to come forward. The three offenders are described as white and wearing dark clothing with scarves and gloves.
Detective Constable Suzanne Rigby, of Wigan CID, said: “The people we are looking for are clearly very determined robbers not afraid to use violence and intimidation, so it is very important we catch them.
“I want to appeal to anyone who might be offered jewellery from anyone other than a licensed dealer to call us. These men will surely look to sell these goods on the black market, so if you are offered jewellery and are suspicious, call us immediately.
“I also want to hear from anyone who saw the pale blue Golf near the robbery, or who has seen the stolen red Mini.”
Anyone with information should call Wigan CID on 0161 856 7295 or Crimestoppers, anonymously, on 0800 555 111.
