A woman who offered a bribe to a police corporal to be lenient to her husband caught speeding was jailed for two weeks and fined $2,000.

Designer artist Yu Jie, 31, admitted to offering $50 to corporal Kevin Koh Chee Seng so that he would reduce her husband's offending speed of 115kmh to 109kmh at Tampines Expressway on March 20 (07).

She did this to enable her husband, Mr Liu Leming, to get less demerit points as he had previously been issued with six demerit points for speeding along the Pan-Island Expressway.

As a probationary driver, Mr Liu was allowed to accumulate up to 12 demerit points.

Cpl Koh had stopped the couple's car along the expressway which has a speed limit of 90 kmh.

The officer rejected the couple's pleas and proceeded to record the summons.

Yu then took out $50 from her waist pouch and said to Cpl Koh: 'This is for you to buy cigarettes.'

When Cpl Koh turned down the offer and warned her that bribery was a serious offence, she kept the money.

She could have been fined up to $100,000 or jailed for up to five years or both for corruption.
