Detectives investigating football gang rape claims were reported Wednesday to be set to request DNA samples from the accused soccer stars.
The move came as details emerged of how the men who allegedly raped a 17-year-old girl laughed as they took turns to assault her, the London Evening Standard reports.
The alleged victim, a pupil at a Catholic school, has shown family members bruises she says were inflicted in the attack at the Grosvenor House hotel in Park Lane.
She claims she was willingly having sex with one of the players when seven others walked in. She claims several then raped her.
A police source described the girl's story as "credible".
Many items, including sheets, towels, drinking glasses and refuse, were removed from the room for forensic testing.
It is believed the Premiership player who booked the room has proved he did not stay there and is denying any involvement.
At least four of the seven others play for Premiership clubs.
The Sun adds that the girl admitted to relatives that she went to London's Grosvenor House Hotel last Friday night and agreed to go to bed with a footballer.
She told her family she recognised only one of the seven
because he plays for the club she supports and that he humiliated her verbally as he allegedly forced himself on her.
A source close to the family said yesterday: "She is still in shock and can't stop shaking whenever she talks about it.
"She has admitted that she consented to sex with one of the players, but says she was horrified when the rest came in.
"She claims she was forcibly raped by three or four of them on the bed. One was allegedly holding her down by the arms, calling her a s**g. It left her degraded and utterly humiliated."
Details of the girl's claims emerged yesterday as the allegations continued to be probed by Scotland Yard's Operation Sapphire specialist sex offences unit.
The girl gave a full statement to cops about her alleged ordeal after reporting it at Marylebone Police Station over the weekend.
In conversations with family members, she said she went with a girlfriend to a makeover party in the West End prior to her first meeting with the stars.
She and her chum are said to have looked much older than their years when they went out on the town afterwards.
The alleged victim a tall, slim part-time model with shoulderlength brown hair met one of the players at the Purple Bar in London's Sanderson Hotel.
The teenager told relatives the athletic star chatted her up before she agreed to go with him to the Grosvenor House.
Witnesses told The Sun football-
ers were seen chatting with two girls in the hotel's Red Bar.
The girl claims she drank only Coke throughout the evening and was sober when she agreed to go to the star's room.
But as the pair had sex, she claims she fell victim to the gang rape.
The source said: "She alleges they were all over her like animals.
"She said she walked out of the room without saying a word when it was over, with the players' laughter ringing in her ears.
"She got the lift down and called herself a taxi home."
According to the source, the girl at first felt unable to tell her mother her shocking story.
But she tearfully poured out details of the alleged attack to her older sister and went to police the following day.
The family source said: "Her dad wanted to kill the players responsible and it was made worse by the fact some of them played for his favourite team.
"His daughter only turned 17 recently. He keeps saying, 'How can they do this to my girl'?"
The girl, who has been tested routinely for HIV and date rape drugs, claims two of the eight players were from one Premiership club, with six from another.
Her pal, who is understood to have stayed with the stars at the hotel bar when the alleged victim went upstairs, could also be crucial to the investigation.
She is said to be a keen football fan who could identify all the players she met.
