A woman aged in her early 60s was forced to hand over a gold Rolex watch, with a diamond encrusted bezel worth around £20,000, when her partner was threatened with a shotgun.
The partner answered a knock to the front door when he was confronted by two men, one of whom had a shotgun or rifle, who demanded cash and jewellery. The other man then brought the woman victim from a bedroom where she was forced to hand over the watch when the robbers threatened to shoot her partner.
The robbers then ran from the premises and got into a car, possibly a light grey Ford Focus. Neither victim was harmed other than being traumatised by the event.
The men are described as both white and in the 20 to 40 age range.
Anyone with information that could assist detectives investigating the robbery is asked to call police at South Ockendon on 101 or 0300 333 4444, or call Crimestoppers on 0800 555 111.
