Police have released CCTV of a man they want to speak to in connection with a series of alleged incidents of indecent exposure and false imprisonment.
Police in Westminster are investigating the allegations, said to have taken place at a fast food restaurant in Paddington, and have appealed for the latest victim to contact them, and for any witnesses to get in touch.
The latest incident occurred on Saturday May 16 at around 9.45pm at the Burger King on Praed Street, W2.
A woman, believed to be in her 30s, informed staff that there was a man in the women's toilets who exposed himself and made sexually indecent gestures towards her.
She also stated he had followed her out of the toilets and down the stairs but had left through the fire exit on the first floor.
This victim left the venue before speaking to police and officers are appealing for her to contact them.
Two previous alleged incidents at the same fast-food restaurant have also been reported to police.
The first took place on Sunday March 22, at around 9.30pm, while the second was on Wednesday April 15 at 6.30pm.
In both incidents the victims were 16-year-old girls and both were prevented from exiting a cubicle, subjected to the suspect exposing himself and making sexually indecent gestures. In both incidents the suspect exited via the fire exit on the first floor.
The suspect from all three incidents is believed to be the same individual.
He is described as white man with short black hair, aged between 30 and 35-years-old, around 5ft 11ins tall, with a stocky build and is believed to be of eastern European origin.
At the time of the third incident he was reportedly wearing a blue jacket with blue jeans, dark-coloured shoes and was carrying a black bag.
Trainee Detective Constable David Roberts, from Westminster's serious crimes unit, said: "We are releasing CCTV footage of the man in connection to this incident and are asking for the victim as well as witnesses to come forward.
"This type of crime is very upsetting for the victims; I am keen for anyone with information to please come forward. We will investigate every lead."
Anyone with any information is asked to contact Westminster police's CID on 101 or Crimestoppers anonymously on 0800 555 111. If the suspect is seen please dial 999 immediately.
