A 46-year-old woman has been raped in the west end of Glasgow while returning home from a night out with friends.
The woman was attacked by a man in Commore Drive, Knightwsood, at about 0100 BST on Sunday, shortly after being dropped off by a taxi.
The suspect was described as white, in his 30s, about 6ft, of medium build, and unshaven with short, dark hair.
He was wearing a dark-coloured track suit with white trainers. He also wore a stud earring in his right ear.
Police said the woman got into the taxi with a female friend following a night out.
They picked up a male friend while travelling home and both the man and woman were dropped off in the Drumchapel area.
The 46-year-old woman was dropped off at Alderman Road, at its junction with Dyke Road, where she paid the taxi driver and began to walk home.
As she turned into Commore Drive from Alderman Road, she was grabbed by a man who then raped her.
Det Insp Stephen Healy, from Strathclyde Police, said: "This has been a dreadful assault on a lone female coming home from a night out.
"She is extremely traumatised and upset by what has happened and it is imperative we trace the person responsible. I would like to reassure the public that although this type of random attack is rare, additional police patrols will be carried out in the general area.
"I would like to speak to the taxi driver who drove the group of friends home. It's possible he has important information which could lead us to the suspect.
"I would also appeal to other taxi drivers who were in the area around the time of the incident - one of them may have seen a man fitting the description of the suspect and I would appeal to them to get in touch with us as a matter of urgency."
Officers have stressed that the taxi driver who dropped the woman off in Knightswood is not being sought in connection with the incident.
