POLICE arrested a 41-year-old drink driver early on Friday morning after a a tip-off from a public-spirited citizen who trailed the car for a distance.

Mr Chia Hong Boon, a 27-year-old project manager, was driving along the Central Expressway towards Tampines Expressway at about 5.05 am, when he noticed a car driver driving in an unsteady manner.

Mr Chia decided to follow the car from a distance and called the police for assistance.

He notified the police when the car driver drove into an open carpark at Block 231 Ang Mo Kio Street 22 and kept watch while waiting for the police.

The driver was about to drive off from the car park when the police arrived and arrested him after he failed a breathalyser test.

A subsequent breath analyser test showed that the car driver's breath contained 80 microgrammes of alcohol per 100 ml, significantly exceeding the legally prescribed limit of 35 microgrammes per 100 ml of breath.
