A former wife of alleged match-fixer Dan Tan Seet Eng appeared in court yesterday to answer a charge of giving false information to the Corrupt Practices Investigation Bureau (CPIB).

Guan Enmei's case was fixed for mention for the 40-year-old Singaporean to plead guilty, but she denied the charge. She said: "I did not give false information."

She is accused of knowingly giving false information to a senior special investigator at the CPIB premises in Lengkok Bahru on June 6, 2013. She allegedly said she had left her house with only her handbag and denied taking with her a paper bag with two laptops - which she knew to be false, according to the charge.

Guan, who is unrepresented, told District Judge Chay Yuen Fatt that she wanted to have the case concluded so that she could take her son to China for his education.

The judge told her he could not accept a plea out of convenience. Her case is fixed for a pre-trial conference on Jan 28. She is out on $10,000 bail. If convicted, she could be fined up to $10,000 and jailed for up to one year.

Tan, described by Interpol as "the leader of the world's most notorious match-fixing syndicate", is being detained without trial under the Criminal Law (Temporary Provisions) Act for the second time.

He was previously detained for two years, before he was released on Nov 25 last year. The Court of Appeal found that the Detention Order did not expressly show Tan's activities had a bearing on the public safety, peace and good order within Singapore.

After being re-arrested on Dec 1, a new Detention Order showing the extent of his match-fixing activities from and within Singapore was issued by Home Affairs and Law Minister K. Shanmugam, with the Public Prosecutor's consent.

Yesterday, Tan's lawyer Hamidul Haq said: "We are studying the legal avenues available to us to address the new detention order."
