This is the moment a "young man" wanted by police in connection with a series of sexual assault and exposure incidents was caught on CCTV peering over a fence.
Thames Valley Police released the image of the suspect looking into a property in Newbury, Berkshire.
The force is appealing for information following four incidents in the area in the past six months.
In the first, reported on 27 March in Hutton Close, a man entered the car park of the Willows Edge Care Home and exposed himself from the waist down.
In the second incident, at about 9.35pm on 21 May, a man was standing on the other side of a fence behind properties on Huntington Gardens.
He was naked from the waist down and performed an indecent act while looking toward the properties.
He was aware he had been spotted but this did not deter him.
He only left when a member of the public called the police.
In the third incident, at about 11.30pm on 17 June, a woman was walking past the Riverside Community Centre when a man with no trousers on approached her from behind and touched her inappropriately over her clothing before running away.
The fourth and final incident happened at 11.50pm on 1 July, when a man was seen loitering in Shaw Park by a female dog walker.
Police said he followed her out of the park on to Dene Way, where he exposed himself and performed a sex act in front of her as she stood under a streetlight.
The woman immediately called the police and the man turned and ran back towards the park.
Police have released two images of the suspect.
Detective Inspector Bill Sykes said: “I am appealing for information about four separate incidents where we believe the same young man was involved.
“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.
“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.
"Someone must know who he is."
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.
“I would encourage people to please come forward if you recognise this man or have any information about him or the incidents, which could help our enquiries."
Anyone with information can contact police on 101 or by calling Crimestoppers anonymously on 0800 555 111.
