Detectives are investigating after an attempted aggravated burglary in Hampton was foiled by the quick reactions of two women.
Police were called at approximately 13:00hrs on Friday, 3 November to reports of an attempted burglary at an address in Uxbridge Road.
The homeowner was inside with a friend, when they heard a loud persistent knock at the door. The friend went to answer and a man armed with a handgun attempted to force his way into the property.
The friend said: "I looked down because I was expecting him to have a parcel and I just saw the barrel of a gun in his right hand. I instantly started screaming and pushing at the door."
Together the women - both in their 40s - managed to force the door closed and stop the man from entering. No injuries were reported and no shots were fired.
The man then fled on foot from the address, down the driveway and turning right towards Hampton Hill High Street.
The suspect is described as a black man, aged between 20 and 30, 6ft 3ins tall, of slim build, wearing black skinny jeans, a black t-shirt, black jacket and a black beanie hat.
Detectives investigating the case believe the suspect may have been trying to target another address and fled after realising he was at the wrong property.
Detective Constable Mike Svensson of the Met's Flying Squad who leads the investigation said: "This is an unusual and shocking incident where two women were forced to stop a man armed with a gun entering a house in the middle of the day. It is unclear why this property was targeted, and this forms part of our ongoing investigation.
"The victims have been left terrified and I would urge anyone with information about this incident to get in touch as soon as possible."
The homeowner said: "I will not answer the door to anyone anymore. My chain is on constantly - I have never ever lived like this in my life."
She believes that she saw the man earlier in the day walking past her house.
No arrests have been made and officers from Richmond and the Met's Flying Squad continue to investigate.
