A teenage girl was sexually assaulted in Ilkeston last weekend, police have revealed.
The 16-year-old was walking along Hillingdon Drive at about 12midnight on Saturday June 23, when she saw a man, who she thought she knew.
She started talking to him and as they chatted he grabbed her bottom. She shouted at him and the man then threatened her and she ran off.
This morning, Derbyshire police has released an evo-fit image of a man they believe to be the offender.
The girl described him to officers as white, about 20 years old, and of very skinny build.
He was between 5ft 3ins and 5ft 4ins tall, with short black shaven hair, a thin face and thick eyelashes.
He was wearing a red flat peak cap with a gold swirl on the front, a baggy jacket, very baggy jeans and chunky white trainers.
Anyone who recognises the man or has information about the assault should call Pc Andy MacAlister on 101 or Crimestoppers on 0800 555 111.
