Police are appealing for witnesses and information following a sexual assault in Hounslow.

At approximately 21:40hrs on Wednesday, 6 May, a woman in her 40s was approached by four to five men as she was walking along Kingsley Road, junction with Cecil Road. She was subsequently assaulted.

One of the men from the group slapped and then sexually assaulted the victim.

There was then a short verbal exchange between the suspect and victim whilst the rest of the group closed in on her.

The main suspect then made further physical contact with the victim.

He then walked away from the victim close to Hounslow bus garage in London Road along with the rest of the group.

All of the men are described as Asian in appearance and the main suspect is approximately 25-29 years old, approx 5ft 9ins in height and wore dark trousers and a white t-shirt.

Detective Sergeant Jason McElroy said: "We are keen to trace one witness in particular who is described as an Asian man who had been in close proximity to the victim at the time of the incident. This was clearly a distressing incident for this victim who was intimated and assaulted along a route which she routinely walks."

Anyone with information is urged to call the incident room on 0208 247 6273 or if you wish to remain anonymous call Crimestoppers on 0800 555 111.

No arrests and enquiries continue.
