AN URGENT hunt is on for a sex attacker behind a series of vile assaults – and police have released creepy images of him peering over a fence.

The man is wanted for a number of chilling crimes committed in the dark of night, including approaching a woman from behind and sexually assaulting her before running away.

He is also wanted for exposing himself near a dementia care unit, and lurking in the darkness before following a dog walker and performing an indecent act in front of her.

Every crime reported has involved the man being naked from the waist down.

Police are aware of four incidents of sexual assault or exposure in Newbury, Oxfordshire, that they believe the man has been involved in.

Thames Valley Police have today released photographs of the suspect, as well as more information about his "very concerning and inappropriate" crimes.

Girl, 17, suffers ‘serious sexual assault’ as cops launch hunt for attacker

Police said the first was reported on March 27 when a man entered the car park of the Willows Edge Care Home, a dementia care unit, and exposed himself from the waist down.

Then, two months later on the evening of May 21, a man performed an indecent act from behind a fence while looking at properties in Huntington Gardens.

The man did not stop when he knew he was spotted.

On June 17, at around 11.30pm, a man with no trousers on allegedly approached a woman from behind as she walked past a community centre.

The man sexually assaulted her by touching her over her clothing, then ran away.

The final reported incident happened around 11.50pm on July 1 when a man was seen loitering in a park by a female dog walker.

He stayed in a dark area of the park and waited for the woman to walk past him before following her to a street, where she stood under a streetlight and waited for him to pass.

As she turned around, she saw the male expose himself and perform an indecent act.

The woman immediately called the police and the male turned and ran back towards Shaw Park.

Thames Valley Police Detective Inspector Bill Sykes said: "We are yet to identify him, therefore, I am appealing to the public for any information, as someone must know who he is.

"This is obviously very concerning and extremely inappropriate behaviour so it's important we identify and speak to this person as soon as possible.

Somebody must know who he is.

"There may be incidents that have not yet been reported to us and I want to encourage any victims who have not yet contacted us to do so."

He added: "Someone must know who he is."

Two images have previously been released of a man officers believe may have vital information about the first two incidents.

DI Sykes said officers are conducting extra patrols across Newbury and members of the public should feel free to speak with them about any concerns they have.

He said: "We have several images of a man who we believe may have vital information about these incidents, but I appreciate the quality is poor.
