Police have yet to speak to a taxi driver who picked up the suspect after a woman was raped in Edinburgh.
The 33-year-old had been out in Leith and was walking home on Anderson Place when she was attacked just after midnight on Sunday.
The man, who had a skateboard, stopped the woman and asked her for directions to Ferry Road before ushering her on to the path leading to the Water of Leith walkway, where he carried out the sex attack.
Detectives investigating the case are keen to speak to a taxi driver who picked up the suspect on Ferry Road, at the corner of Newhaven Road, after the attack.
The taxi driver is yet to come forward and police believe he can help with their investigation.
Detective chief inspector Martin MacLean told STV News: "We're appealing for that taxi driver to come forward, he or she has not thus far.
"So please, if you're the taxi driver and you made a pick-up in this area of Ferry Road at the corner of Newhaven Road - please get in touch.
"Our male was carrying a skateboard which is very unusual for that time of night."
The suspect is described as white, between 18 and 24, around 5ft 8in with a slim build with short brown hair close cropped at the back and sides, dark stubble and prominent dark circular earring in one or both ears.
In addition, he was wearing a camouflage patterned hooded jacket, blue jeans and trainers.
He had earphones and was wearing a rucksack on his back and was carrying or using a skateboard.
The suspect is thought to have a possibly Irish accent, although this is not certain, and he seems not to know Edinburgh well.
