Pop singer Jeremy Liu, 24, was arrested yesterday on suspicion of drink-driving after his Alfa Romeo crashed into a flower bed at a tunnel entrance. Police said initial tests indicated Liu's breath-alcohol level was about three times the legal limit. Liu, the holder of a Hong Kong identity card, and his passenger, Lin Ya-lin, also 24, from Taiwan, were slightly injured. They were in stable condition in the United Christian Hospital last night. Police sad Liu was driving along Tseung Kwan O Road, Kwun Tong, at about 5.30am when his white Alfa Romeo 159 saloon crashed at the entrance of the Tseung Kwan O Tunnel. 'The vehicle ran out of control and crashed into a flower bed near the tunnel's administration building after driving past a pay booth,' a police spokesman said. The car then mounted the flower bed and toppled on to one side. The occupants were trapped and had to be freed by fire-fighters. Liu suffered minor injuries to his forehead, arms and legs. Lin suffered an injury to her right hand and pains in her abdomen. They were taken conscious to hospital. Liu was arrested after a breathalyser test showed his breath-alcohol level was over 60 micrograms per 100 millilitres, well above the legal limit of 22mcg/100ml. He has been released on bail of HK$5,000 and will have to report to police in July. A spokeswoman for Warner Music said the road had been slippery and Liu had drunk some alcohol at his birthday party at home yesterday morning. She said Liu had just returned from Taiwan, where he drove on the other side of the road. In a separate case, police arrested a motorcyclist for drink-driving in Kowloon City early yesterday. The 53-year-old man was driving along the Prince Edward Road East flyover near the junction with Choi Hung Road when his motorcycle crashed at about 2am. He and his passenger, 42, left in a minibus before police arrived. Officers stopped the minibus about 1km away. The motorcyclist was arrested after he failed a breathalyser test. The two men were treated for minor injuries at Queen Elizabeth Hospital.
