THE China-born wife of opposition politician Tan Lead Shake, accused of murder, was charged on Monday with two more offences.

Wu, 25, was charged last week with the murder of her brother-in-law Tan Lead Sane, 34, a computer engineer, at their Paya Lebar Crescent bungalow.

One of the fresh charges accuses Wu of trying to murder Lead Sane's wife, Ms Huang Mei Zhe, 36, by slashing her on the neck between 5.30am and 7am on June 28.

She is also said to have hurt her mother-in-law, Madam Ng Bee Hion, 63, with a knife.

Mr Tan Lead Shake sat in the courtroom for about an hour on Monday before he left at about 10am, without waiting for his wife's case to be brought up.

He was dubbed the 'Slipper Man' after he turned up in rubber flip-flops on Nomination Day.

He had contested unscucessfully in three previous general elections - at Kampong Glam and Ayer Rajah under the Democratic Progressive Party ticket and at Tampines GRC in 2006 under the Singapore Democratic Alliance flag.

Wu will be sent for psychiatric assessment.

Her case will be mentioned on July 28.
