BANGKOK  - Thai immigration authorities said Thursday they would expel former glam rocker and convicted paedophile Gary Glitter to his native Britain after Hong Kong refused to let him in. Glitter, 64, was released from a Vietnamese prison on Tuesday after serving nearly three years for committing obscene acts with two girls aged 11 and 12. He had been booked to fly that night to London via Bangkok, but refused to get on the plane to Britain and instead spent 24 hours in a transit lounge before agreeing to take a flight to Hong Kong. Chinese authorities refused to allow him in and he was sent back to Thailand, where he has been declared persona non grata. A spokesman for the immigration service at Bangkok's international airport said it would return Glitter on a flight to Britain, most likely Thursday night. "We have to expel him to Britain, his homeland and the only country which must allow him to enter as he's a national," Colonel Voravat Amornvivat told AFP. "He's likely to leave tonight but as of now we still can't confirm his flight," Voravat added. Glitter, whose real name is Paul Francis Gadd, has reportedly been contacting countries around Asia in hopes of finding one that will allow him in, but he may finally be forced to return to Britain. Once famous for his flamboyant bouffant wigs and silver jumpsuits, Glitter now tries to hide his scrappy grey goatee behind a scarf to escape the media spotlight as he hops around the region. Glitter had earlier served prison time in Britain on child pornography charges. He was arrested there in 1997 after taking his computer to a repair shop, where hardcore child pornographic material was found on its hard drive. He was sentenced in 1999 to four months in prison, of which he served two. Keen to avoid the media, Glitter reportedly moved to Cuba and then Cambodia, where he was expelled in 2002, allegedly for trawling for underage sex. Having settled in communist Vietnam, where a British newspaper reported he was living with an underage girl, he was arrested at Ho Chi Minh City airport in November 2005 while trying to leave for Thailand. In March 2006 he was sentenced to three years in prison, the minimum term under Vietnamese law, which was later cut by three months. The singer maintained his innocence, blamed a media conspiracy and claimed he was teaching the girls English and allowed them to stay overnight because they were scared of ghosts. He has continued to profess his innocence as he shuttles desperately among Asian airports. "God, am I happy to be leaving Vietnam and that jail. I should never have been in there," he said on one flight, according to The Sun newspaper in Britain. Although Britain has not announced any outstanding charges against the singer, Home Secretary Jacqui Smith said he would be forced to sign a sex offenders register and warned that he should not be allowed to travel overseas again. In the 1970s, Glitter racked up several hit songs including "I'm The Leader Of The Gang (I Am)" and "Do You Wanna Touch Me?" The anthemic 1972 hit "Rock and Roll" is still often chanted in British and US sports stadiums. He has spoken about trying to revive his music career and penning a book that he says would exonerate him.
