A teenage girl has been raped by two men on a double decker bus as she left a shopping centre with her friend.
The 14-year-old was attacked on the top deck of the 57 bus as it left Silverburn shopping centre in Pollok, Glasgow, at about 10.30pm on Friday.
When the girl and a friend got on the bus, they took a seat downstairs. The victim went to the upper deck where she got into a conversation with two men who boarded the bus in the city centre.
She was then assaulted and raped by both of them. Her friend, also 14, went up to see her and raised the alarm with passengers downstairs. A woman and two men came to the girls' aid. They all left the bus two stops along from Silverburn.
The passengers are said to have waited with them until they got another bus home, where police were contacted.
No CCTV footage is available from the bus and Strathclyde Police is appealing for those passengers to come forward to help their investigation.
Both of the attackers are said to be aged around 18 to 20. One is about 5ft 10in, with a shaved head and wearing a black jumper. The other man has brown, spiky hair and was wearing a tracksuit which may have been grey, with a body warmer or jacket.
Detective Constable Jackie Carroll, from Greater Glasgow CID, said: "We're continuing extensive inquiries into the incident and would like to trace two men and a woman who came to her assistance as they will have vital information which could help with our investigation.
"We know that the men responsible boarded the bus in the city centre. The men were very loud and using crude and lewd comments to other passengers. The bus driver ejected the two men from the bus at Pollokshaws Road (near Queen's Park) around 12.30am."
