A British pop legend under investigation for allegedly raping a 14-year-old girl is petrified his identity will be unmasked after he was named online.

Video of the alleged victim naming her attacker and recounting her rape ordeal has already been viewed thousands of times in America.

And in further pain for the singer, who cannot be named for legal reasons – he was pictured alongside her on a US news website.

The unnamed superstar has not been arrested, questioned or charged with any offence, according the The Sun, is said to be “petrified” the allegations will destroy his reputation.

The attack allegedly took place in the 1970s after the girl, who was a virgin, was picked out from the front row of a concert by the solo star's bodyguard and invited back to a hotel.

The woman says she was plied with champagne before the assault, that has "affected" her entire life.

The alleged victim, who describes herself as a "naive 14-year-old virgin" at the time, says she had been to see the singer in concert with some friends after being given free tickets.

She told The Sun that she had never even "French-kissed" a boy at the time and that she couldn't understand the look on the star's face when he was "probably climaxing".

Police are reportedly looking into the claims and she met with detectives last week.

It's alleged that the woman and her friends were invited to the singer's hotel the following day by a bodyguard who had spotted them giggling near to the stage.

The girls, 13 and 14 at the time, went along hoping to meet the pop star and get his autograph.

The newspaper reports that an aide separated the girls and the alleged victim was taken to a suite where a comedian, a female pal and a backing singer were relaxing when the star walked in wearing a short white robe.

The woman, now in her 50s, says she was led to the balcony and offered a glass of champagne and took it to be "part of the crowd".

She said: "Before I knew it, it was like an immobility had set in there and then. He had me down on the bed in one fell swoop.

"His gown was off. I was wearing a jumpsuit. He zipped it down and what had started as ­affectionate and safe, almost, was suddenly becoming painful and forceful, not comfortable."

She says she couldn't understand where the pain was coming from and that the star told her it wouldn't hurt if she relaxed.

The woman says she left the room before going back because she had forgotten to get his autograph.

And when she went back, she says the star cupped her face and promised to stay in touch.

She added that she only realised later when she was showering that she was covered in bruises and that she'd been traumatised for years over the incident that she was too scared to tell her friends and family members about.

She said what happened left her obsessed with the singer and unable to have normal relationships with men.

In 2013, she emailed her allegations to Scotland Yard, but as it happened overseas, it was out of their jurisidiction.

An official probe was reportedly opened by police in 2014, but dropped six months later.

However, it was disclosed last month that a new prosecutor and investigating officer had been assigned to the case.

A spokesman for the prosecution service told the newspaper: "The case has been referred to police with a request for further investigation."
