Police are investigating after a teenage girl was allegedly raped in an evening assault in Dundee.

The 18-year-old was subjected to a serious sexual assault in West Henderson's Wynd at around 8.15pm on Thursday.

The male attacker ran off after members of the public came to help her.

Police have appealed for information.

Detective Chief Inspector Graham Binnie said: "Firstly I would like to say that this is an extremely distressing incident for the 18-year-old female victim and she is being supported by family and friends, along with specialist officers.

"This is a horrific crime but I would like to stress that incidents of this nature are very rare and our priority is to identify and find the person responsible.

"I would appeal to anyone who was in the area between 8pm and 8.30pm, either on foot or in a vehicle, to come forward because you might have vital information that can assist our enquiry.

"Also, anyone who lives or works in the area, we would like to hear from you. Lastly, I would appeal to anyone who might know the identity of the person responsible to come forward."

The victim was wearing a distinctive yellow jacket at the time of crime and police hope that someone might remember seeing her.
