A woman has been left with serious facial injuries after a "vicious and unprovoked" assault on her own doorstep in Edinburgh.
The 25-year-old was inside her flat in Niddrie at 0300 GMT on Saturday when she heard a group of men and women arguing in the street.
The group then entered the victim's block and knocked on her door.
After answering and telling them to leave, she was punched and kicked several times by one of the women.
The victim was taken to Edinburgh's Royal Infirmary, suffering fractures to her cheek and jaw.
The attacker is white, in her late 20s, 5ft 9ins, with "droopy" facial features, of thin build and with short-dyed ginger-frizzy hair.
A Lothian and Borders Police spokesman said: "This was a vicious and entirely unprovoked assault which left the victim with serious facial injuries, and we are appealing for help in tracing the culprit.
"Anyone who saw a group of men and women arguing in Niddrie House Park in the early hours of Saturday morning, who has any information that can help our inquiries, should contact police immediately.
"Similarly, anyone who recognises the description of the suspect should also get in touch."
