Swedish detectives are investigating allegations that a woman was gang-raped in an attack that was broadcast on Facebook Live.
A witness who watched the incident online said she saw the victim being stripped and then sexually assaulted by several armed men and said the attack only ended several hours later when police arrived and switched off the webcam.
The Swedish newspaper Aftonbladet said the assault took place in a flat in the town of Uppsala, north of Stockholm, on Saturday night and three people had been arrested.
Police were alerted by Josefine Lundgren, 21, who looked on in horror as she watched the live stream on a closed Facebook group.
She told Sweden's Expressen newspaper: 'He pulled her clothes off and lay on top of her.'
Ms Lundgren said she saw uniformed police arrive at the scene and arrest the culprits.
Another online witness told the paper: 'At first I thought it was a poorly orchestrated joke.'
He said: 'The first thing you think is "how can you do such a thing to a girl?" And how can you do it live? It is totally sick.'
The apartment is being examined by forensic scientists, three men are being questioned and the woman is thought to be recovering in hospital.
In June last year gang member Antonio Perkins, 28, unwittingly live streamed his own death on Facebook after he was shot dead in Chicago while using the real time video app.
And earlier this month four black people were charged with a hate crime after a white man with learning difficulties was tortured on Facebook Live. The gang shouted: 'F*** Trump' and 'F*** white people' during the attack, also in Chicago.

On Flashback, the men accused of the rape are identified as Middle Easterners. The rape was conducted at an address in Uppsala, and the men filmed themselves and sent the assault live via Facebook.
According to a person who saw the live broadcast, the woman who was raped looked "quite intoxicated" and appeared "completely dead" while one of the men molested her. Several people alerted the police when they saw the film.
The live broadcast on Facebook was not stopped until the police stormed into the room where the woman and the men were. The men will now be interrogated by the police.
- Before prosecutors can make a decision, the policemen have to document everything, a complaint, write down observations and conduct interviews with those who have something to say. Once that is done, they will present it to the prosecutor, so it takes time, says Aslund.
He is otherwise very secretive about the investigation and would not say anything about the rape that was sent live worldwide on Facebook from the new Sweden.
The last transmission shows the police breaking into the apartment and arresting the rapists.
