Burglars smashed their way into a house on Bilton Lane before stealing watches and jewellery on Monday, October 26.
The suspects entered the house in broad daylight by smashing a window on a rear patio door before removing various items from the property.
Officers investigating the scene later discovered a TV from inside the house abandoned on the victims' garden, believing they may have been disturbed during the attack.
Eye-witnesses reported seeing an unmarked white van containing two white men outside the property at 9.30am
House-to-house interviews and forensic enquiries at the location are currently ongoing as well as reviews of CCTV coverage in the area.
