When Shaw family scion Howard Shaw Chai Li, 46, was stopped while driving along Whitley Road at around 3.45am on Jan 31, he allegedly had 88 micrograms of alcohol in 100ml of breath.
This is more than double the prescribed limit of 35mcg.
It is the third time he is accused of drink driving.
If convicted, Shaw is liable to receive an enhanced punishment and can be jailed for up to three years, court documents show.
Yesterday, the grandson of Mr Runme Shaw, the founder of the Shaw Organisation, was in court with his lawyer Terence Tan to face the latest drink driving charge.
According to court documents, the former green activist was previously convicted of drink driving in 1997 and 2006.
In 1997, he was fined $3,000 and disqualified from driving for two years. He was jailed for a week, fined $8,000 and disqualified from driving for four years following the conviction in 2006.
In Singapore, first-time drink drivers can be jailed for up to six months or fined between $1,000 and $5,000. Second-time drink drivers can be jailed for up to a year and fined between $3,000 and $10,000. Recalcitrant offenders who receive an enhanced punishment can be jailed for up to three years and fined up to $30,000.
Shaw, who is the senior vice- president of corporate social responsibility of investment holding company Halcyon Group, is out on bail of $10,000.
He will be back in court on March 30.
