SINGAPORE - The Attorney-General's Chambers (AGC) has filed an application to the High Court to challenge the decision to grant former China tour guide Yang Yin bail.

The AGC said that the criminal revision was filed in the High Court on Nov 7, one day after the State Court had decided to grant Yang bail of $150,000.

A criminal revision is a where the High Court reviews the record of proceedings before a State Court to correct any irregularity in the decision of that court.

The court hearing for this application will take place on Nov 10.

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

Yang now faces 331 charges in total for falsification of receipts made to his company Young Dance and Music Studio.

If convicted, he faces 10 years' imprisonment, a fine or both.
