A bail application by former singer Gary Glitter is being considered by the Vietnamese authorities, officials say.
Glitter was stopped at Ho Chi Minh City airport on 19 November
Glitter, 61, is being held under suspicion of committing lewd acts with children, which he has denied. He has not been charged.
The former star's Vietnamese lawyer has proposed to pay the maximum $40,000 (£23,000) bail money, AFP reported.
A state official from Ba Ria Vung Tau province told Reuters he would not be allowed to leave the country if bailed.
His lawyer Le Thanh Kinh said he believed his client - whose real name is Paul Francis Gadd - would be held for at least one more month for questioning before any bail was granted.
Glitter's detention was last week extended by four months while claims he had sex with under-age girls, one aged 12, are investigated.
The girls are said to have had sex with the 1970s rock star at his home in the resort of Vung Tau, where he has lived for the last six months.
Glitter's lawyer has called the allegations "hearsay".
Under Vietnamese law, Glitter can be held for up to 12 months before charges are laid.
If convicted, Glitter could be jailed for up to 12 years.
The 1970s rocker was held on suspicion of committing lewd acts with children after an arrest warrant was issued earlier this month.
He was stopped at Ho Chi Minh City airport on 19 November by an official who recognised him from media coverage.
There are conflicting reports as to whether the second girl linked to the alleged acts had turned 18 - the legal age of consent in Vietnam.
Glitter was found guilty in the UK in 1999 of possessing child pornography and served two months in jail.
