SINGAPORE- Former China tour guide Yang Yin has been remanded while the High Court deliberates over whether to reverse an earlier decision to grant him bail.

The Attorney-General's Chambers (AGC) had filed an application to the High Court last week to reverse a decision to grant bail to Yang, who is embroiled in a legal tussle over the $40 million assets of a wealthy widow

During the court session on Monday, both the prosecution and Yang's lawyer Wee Pan Lee presented their arguments for and against the earlier decision made by district judge Eddy Tham to grant him bail.

Chief Justice Sundaresh Menon said a decision would be made on Tuesday morning.

The challenge was made last Friday, a day after the State Courts decided to grant Yang bail of $150,000. Yang, who has been detained since Oct 31, has yet to post bail.

This is the latest development in the legal tussle between the 40-year-old Chinese national and the niece of wealthy widow Chung Khin Chun over her assets, which are estimated to be worth $40 million.

Yang faces 331 charges for falsification of receipts worth about $450,000 made to his company, Young Dance and Music Studio.

Deputy Chief Prosecutor Tan Ken Hwee had earlier urged the court to put the bail at $800,000, with four sureties.

He pointed out a recent case in which $600,000 bail and the withholding of a passport were not enough to prevent the accused, facing similar charges, from running away.
