Images have now been released of the property stolen during an aggravated burglary on Fulwith Mill lane.
It occurred at 9.50pm on Sunday 11 May 2014 when three men entered the property before assaulting the owners and stealing a number of high value items.
The 52-year-old man who lives at the property had placed a recycling bin at the front gate when he was grabbed by one of the men as the other two entered the house where they physically assaulted his 54-year-old wife.
After the burglary the men left in a small car, possibly a Volkswagen Golf.
The first suspect is described as being a white man around 5ft 9in to 5ft 10in tall with a stocky build. He spoke with a Leeds accent. He was wearing a dark grey hoody and tracksuit bottoms.
The second man is also white, aged in twenties, approximately 5ft 7in tall and had a stocky build and spoke with a very broad Leeds accent. He was also wearing a dark grey hooded top and covered his face with a black scarf.
The third suspect is possibly of mixed race and around 6ft 2in to 6ft 4in tall with a muscular build. He was wearing a grey hooded top and light coloured tracksuit bottoms and covered his face with a black scarf.
The burglars stole a Cartier Tank ladies wristwatch made of white gold with a diamond bezel and diamond set band, a ladies Rolex Datejust stainless steel with a white shell face and diamonds on the numerals, a yellow gold Rolex Dayonta white face, a Tennis bracelet with diamonds and white gold and a pair of white gold diamond ½” loopy earrings, with diamonds around the side of the earring. They also took a square cut 1.5 carat diamond solitaire engagement ring made from white gold, a white gold diamond ring centre stone with diamonds on shoulder, an iPhone 4S and an iPhone 5S. A Louis Vuiton clutch style handbag in light and medium brown, a Louis Vuiton purse in light brown and tan colour, a Louis Vuiton bi-fold leather wallet with TPA in silver on the outside were also taken.
