Plea to catch man who attacked girl, 17, in Nottingham
Detectives say they believe a man who sexually assaulted a 17-year-old girl in Nottingham may be local to the area.
The teenager was attacked in the Open University grounds, next to Clarendon College, at about 0400 GMT on Thursday.
Police want to trace a man described as mixed race, aged 19 to 20 and over 6ft (1.83m) who was seen talking to her in Mansfield Road just before the attack.
Det Insp Mat Healey, who is leading the investigation, said the victim had suffered a terrible ordeal.
"[She is] understandably traumatised. She's been working with specialist officers over the last two days now and we're continuing to have contact with her.
"Our partners in Rape Crisis and the health service are supporting us in doing that."
