Police investigating a sexual assault in Edinburgh want to speak to witnesses of an 'incident' in a city centre bar.

A woman reported being assaulted at Greyfriars Kirkyard on Thursday January 21.

Investigators are appealing to anyone who was near the Frankenstein bar on George IV Bridge, between 9.30pm and 10.30pm that night, to come forward.

A further appeal is being made for any members of the public who saw a male and female leaving Greyfriars Kirkyard at around 10.30pm to make themselves known.

Detective Inspector Tom Carty of the Specialist Crime Division in Gartcosh, said an 'extensive inquiry' was underway.

He said: “We’re currently pursuing a number of lines of inquiry and as a result of this work, we’ve established that a group of males and females were within the bar prior to this attack.

“I want to hear from anyone who may have have been in the premises on Thursday evening to contact police.”

Anyone with information that can assist is asked to contact police on 101 or the Crimestoppers anonymously on 0800 555 111 or speak to local officers.
