Three masked men raid store, stuffing jewels and cash into bed cover.
Armed thieves have targeted a branch of UK pawnbroker H&T in Leigh, Greater Manchester, stealing around £20,000 of jewellery before fleeing in two stolen cars.
The branch of Harvey & Thompson was targeted last Thursday at around 5pm, when a trio of three masked men stormed into the store, with two forcing staff to open the window cabinet while the third threatened staff, telling them to open the cash register.
The thieves are said to have stuffed their loot of silver and gold jewellery into a brown duvet cover, before fleeing in a stolen pale-blue Volkswagen Golf, which they set fire to, before switching to a stolen red Mini.
The thieves broke into a property some 10 miles away from the raid, where they stole the cars.
No one is thought to have been hurt in the incident, but police are appealing for witnesses. The three men are described as white, wearing dark clothing, scarves and gloves.
Detective Constable Suzanne Rigby 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 and profit from their criminality, so please if you are offered jewellery and are suspicious, call us immediately.
The public are also being asked to come forward if they saw a speeding blue Gold or red Mini in the area close to the H&T raid, or if they have information relating to the two cars.
Anyone with information should call Wigan CID on 0161 856 7295 or Crimestoppers, anonymously, on 0800 555 111.
