THE Vietnamese woman convicted of bigamy and other offences last week lied repeatedly to immigration authorities over her five years here to prolong her stay.

Yesterday, Husband No. 3 was found guilty of abetting her in her false declarations to the immigration authorities and in committing bigamy.

The Kuan Meng, a 36-year-old sales engineer, could face seven years behind bars.

He married Tran Thi Gai, 29, while she was still married to her first husband, Mr Liong Tian Yong.

Last week, Tran was jailed for 11 weeks. She had married three men in five years.

Yesterday, the court heard how she first married Mr Liong to extend her stay in Singapore. She was then holding a Cambodian passport.

In 2003, she took Husband No. 2, Mr Kelvin Quek Tze Beng, under another name.

In August 2004, she wed The as she was pregnant with his child - this time, under her real name.

Investigations showed that when she came here in 2002 on a Cambodian passport, she was arrested by anti-vice officers and repatriated.

Once in Cambodia, she surrendered her citizenship and moved to Vietnam. Early in 2003, she was back here on a fake Vietnamese passport. It was at this time that she came to know The. Once again, she was arrested by anti-vice officers and sent back.

Following her second repatriation, she found herself pregnant by The and told him about it.

She entered Singapore again in May 2004, this time on a new Vietnamese passport under her real name, Tran Thi Gai. She married The three months later and gave birth to their first child in September that year.

The court heard that when The filled up disembarkation cards for Tran on their trips to Malaysia, he declared she had never used a passport under a different name - though he knew of her previous run-ins with immigration.

When they got married, he kept mum as Tran declared before the Commissioner of Oaths that she was single - though he knew she was not.

He wanted to go through with the marriage because she was pregnant with his child.

His lawyer Irving Choh told the court that The committed the offences out of love for his family.

He will be sentenced today.
