MASKED men who threatened a family with a knives and hammers during a home invasion in North Yorkshire still remain at large, two years on.

Three men wearing balaclavas broke into the house at Askham Richard on January 26, 2015, and terrorised the family before stealing jewellery, cash and the keys to an E-Class Mercedes convertible, which was later found abandoned.

In January this year, Crimestoppers offered a £5,000 reward to anyone with information which could help police track down the thugs, who police said held the mother at knifepoint with her husband and children, and also kicked the family dog “from wall to wall”.

The woman, who asked not to be named, previously said: “The fact that these boys - and I say boys as they were not men - chose to enter our home when the children were present, makes them beyond heartless.”

North Yorkshire Police previously said the burglary was a targeted attack, and not opportunistic, and left the family “shaken and distressed”, but not physically injured.

A spokesman said the three suspects were all white, the first one had a stocky build, was five feet 10 inches tall, weighed about 16 stone, was aged in his mid to late twenties and was wearing a black, full-face balaclava, but had bulging eyes.

The other two suspects were both in their early twenties with skinny builds and wearing full-face balaclavas. One was about six feet tall, and the other was about five feet eight inches tall.

The thieves also stole a family heirloom during the burglary; a citrine pendant, with pearls around it, on a gold belcher chain, in a white, Ogden’s of Harrogate jewellery box.

Police previously released a CCTV still of a sliver Vauxhall Corsa they believe was connected to the burglary, and appealed to anyone who saw it in the area at the time or can identify the occupants or owner of the vehicle, to contact them.

A spokeswoman for North Yorkshire Police said there had still been no further arrests in connection with the robbery, and urged anyone with information to contact them on 101.
