Police investigating an indecent exposure in a park have released an image of a man they would like to identify as part of their enquiries.

At around 7am on Wednesday July 1, a man exposed himself to a female jogger in Cassiobury Park in Watford.

The woman, aged in her 30s, stopped to call the police but the man left before officers arrived and they couldn't find him.

The police say they have carried out enquiries but have been unable to track down their suspect.

The suspect, who police say made no attempt to touch or grab the woman, is described as white with a tanned complexion and short, dark hair.

He has an angular face but no facial hair. He is approximately 6ft tall and aged in his early to mid-thirties.

Sergeant Chris Parperi, from the Watford local crime unit, said: "We have undertaken lengthy enquiries since the victim first reported this offence to us and reassurance patrols have been increased.

"We have deployed several tactics in order to progress the investigation but we are now releasing this image to the public.

"We appreciate the photograph is of low quality however we owe it to the victim, who was understandably distressed by what happened, to follow up all lines of enquiry in this investigation.

"We are very keen to trace the man pictured because we believe he has vital information that could assist our inquiry.

"If you think you know who is pictured, or you have any further information about this offence, then please get in touch as soon as you can. You could hold the missing piece of the puzzle that could help us make an arrest."
