One bad night may have cost a policeman his career, clean record, pension and driver's licence. Police Constable Ho Ho-chuen, 31, had been on his way home from the pub, where he had been drowning his sorrows after his girlfriend ditched him, when he had an accident driving the wrong way down a one-way street. A breath test revealed 91 micrograms of alcohol per 100 millilitres of breath, nearly three times the legal limit of 35 micrograms. He was convicted of drink driving in December and a magistrate sentenced him to two months' prison, suspended for two years, and disqualified him from driving for two years. He was also was convicted of careless driving and driving with an expired licence and fined $3,500. He had pleaded guilty. But yesterday, Ho went before the Court of First Instance to salvage his career by trying to cut his sentence to a fine. Government officers fined for criminal offences only received a reprimand from employers, said defence barrister Thomas Iu Poon-shing. 'The difference between a fine and a suspended sentence is devastating,' Mr Iu said. 'A custodial sentence of any kind would jeopardise his career and cost him his pension.' Mr Iu said the sentence was unusually harsh. 'I have not come across a case where a prison sentence has been imposed for similar levels.' Mr Iu said the magistrate should have taken the officer's plight into consideration before sentencing. Ho, a constable with the Wong Tai Sin division, joined the police force 10 years ago. He continues to serve pending his appeal. Mr Justice Michael Hartmann reserved his decision.
