DETECTIVES say they have “exhausted their enquiries” into a violent robbery in which a woman was attacked in her own home in East Barnet.
And they have now appealed to the public for information about the incident in which the woman, in her 60s, was struck with a handgun and had her hands tied behind her back – before jewellery including a diamond ring valued at £75,000 was stolen.
Police are hunting a man described as eastern European, aged around 40, with dark hair, who is aid to have made off from the scene in a black Vauxhall being driven by a second man.
A police spokesman said the incident happened over five months ago, but that initial lines of enquiry have been exhausted and therefore detectives were releasing the images in the hope that someone may come forward.
He said: “At around 9.10am on January 26, a man knocked on the door of a house in Caddington Close, East Barnet pretending to be a delivery driver.
“The victim - a woman, aged in her 60s, who was alone in the house, opened the door and was attacked by the suspect, who pushed her into the house.
“The victim was struck with a black handgun and, with her hands tied behind her back with tape and cable ties, she was forced upstairs.
The suspect stole a number of items of valuable jewellery and left the house, making off in a black Vauxhall Insignia driven by a second man.”
Along with the diamond ring, described as "a Tiffany ring with square emerald-cut diamond," the items of jewellery also include a diamond-encrusted Cartier white gold love bangle valued at £35,000 and Cartier earrings valued at £15,000.
Anyone who may be able to identify the suspect, or has information about the stolen items, is asked to call Flying Squad officers in Putney via 101.
