A young woman has been indecently assaulted in a stairwell as she made her way home from a night out.
The 20-year-old was attacked by a man who followed her into a block in Edinburgh's Barclay Terrace and forced her to the ground, said police.
The incident happened at around 3am on Friday.
Officers have been speaking to residents and examining CCTV footage to try to identify the attacker, who is thought to be in his early-to-mid 20s, has short, dark-brown hair and wore a dark leather jacket and baggy jeans.
Detective Constable Barry Murphy from Lothian and Borders Police said: "While the victim suffered no physical injuries, she was left deeply distressed by this attack and we are keen to hear from anyone who remembers seeing anything suspicious.
"Similarly, anyone who recognises the description of the male, or who has any other information that can help with this investigation, is also asked to contact police immediately."
