A facial reconstruction image has been released in connection with a string of sexual assaults in Watford.

Police hunting a man who has been approaching women and grabbing their buttocks in seven linked incidents since the beginning of June said they want to identify the man as part of the investigation.

The incidents occurred around the Vicarage Road, Wiggenhall Road and Exchange Road areas of Watford.

The offender is described as black male, with a slim build, between 5ft 3ins and 5ft 5ins tall and with short hair. 

Detective Sergeant Matthew Waylett, from the Watford Local Crime Unit, said: "One of the victims has assisted us in creating this image of the suspect. 

"I’d like to hear from anyone who recognises this person or has information about the incidents as a matter of urgency. You can give information anonymously via Crimestoppers if you would prefer. I’d also like to hear from anyone who has been approached in the same way."  

Officers previously released CCTV images of a man they wish to speak to in connection with the investigation. 

Sergeant Waylett added: "The man pictured may have vital information about what happened and I would urge the public to contact us if they can identify him. He is wearing a distinctive pair of Simpson’s cartoon slippers. 

"I’d reassure people that we are taking these incidents seriously and have a number of officers involved in the investigation, as well as increased patrols. I would also reiterate the safety advice which includes remaining alert when walking alone, being aware of your surroundings and sticking to busy areas." 

Anyone with information is asked to contact the local crime unit at Watford Police Station via the Herts Police non-emergency number 101, quoting Operation Cortes. Alternatively call Crimestoppers, the independent charity, anonymously on 0800 555 111.
