Police investigating three armed robberies in Bradford and Leeds have appealed for information.

At about 5.45pm on Monday, 12 December, four men entered a house in Rockland Crescent, Clayton, and demanded to know where one of the occupants was.

Three of the men were carrying knives, while the other was in possession of what appeared to be a sawn-off shotgun.

The men then searched the premises and are believed to have taken a ladies’ Michael Kors watch, before running off towards Woodvale Avenue.

At about 7pm, a man entered a house in Wooler Avenue, Beeston, and made demands for gold jewellery from one of the occupants.

The man, who was believed to be carrying a gun, was followed by four other men who were also carrying weapons, possibly knives.

The men made threats towards the occupants before searching the premises. They are believed to have taken a quantity of jewellery.

At about 7.45pm, three or four men carrying weapons entered a house in Broad Lane, Bradford and ordered the occupants to sit down and be quiet.

The men then made demands and threats for jewellery and cash before leaving with a quantity of cash.

The suspects are believed to be white men in their late teens or early twenties. All wore black balaclavas and black gloves.

Detective Inspector Ryan Bragg, of Bradford District CID, said: “The descriptions of the males involved in these incidents lead us to believe that they may be linked, so we would appeal to anyone who might have seen anyone acting suspiciously in the above areas around the stated times to get in touch.

“A black Mitsubishi L200 vehicle or similar was seen in the area at the time of all three offences and we believe that this was used by the suspects, so I would ask anyone with information about that vehicle to come forward.

“Police are focusing high-visibility patrols in these areas of Bradford and Leeds following these incidents, and we would urge anyone with any concerns to speak to our officers.”

Anyone with information is asked to contact Bradford District CID on 101 or call Crimestoppers on 0800 555111.
