The vulnerable 18-year-old said she was attacked by the migrants at a care home.
She claims the attack lasted a horrifying five-hours at the supervised care facility in Gillingham, Kent where the men were placed by the local council.
Four men, who claim they are all 17-years-old, have been arrested with two of them charged with rape.
Speaking to The Sun, a source said: “She is deeply distressed.
“The victim thinks there were five attackers. The issue is what were they doing there in the first place?
“She is a vulnerable teenager and was under the same roof as some of these suspects.”
The four youths appeared at Medway youth court and have been remanded in custody to appear at Maidstone Crown Court on November 20.
Another two men who were arrested have been released without charge.
Although the suspects are said to be 17, sources say police fear they could be older.
They said: “They arrived in the country without documents claiming to be under 18 and from Syria.
“But the reality is they could be older.”
A Kent Police spokeswoman said: “Four males have been arrested in connection with the alleged rape of a woman at an address in Gillingham, overnight between 31 October and 1 November.
“Two people, thought to be aged 17, have each been charged with rape and remanded in custody until they appear at Maidstone Crown Court on 20 November.
“Two others have been released without charge.
“This remains an ongoing investigation with active enquiries and anyone with information is asked to contact Detective Sergeant Nick Sparkes at Kent Police on 01474 366149 quoting reference XY/038334/15.”
