No defects in brakes as driver had claimed The coach involved in the horrific bus crash on Thursday in Sai Kung was travelling at about 70km/h - 20km/h over the limit - before it smashed into a roadside barrier, killing 18 people and injuring 44, investigators have estimated. Inspections had also found no defects in the coach's braking system, a police source said, following the driver's purported claims that the brakes had failed. The 32-year-old driver surnamed Hung, arrested on suspicion of dangerous driving causing death, was released on HK$30,000 bail yesterday after further police questioning and ordered to report back to police on Tuesday. No charges have been laid. Mr Hung, who escaped serious injury, was quoted by Sai Kung district councillor Yau Yuk-lun on Thursday as saying the brakes had failed before the accident on a roundabout at the junction of New Hirams Highway and Nam Pin Wai Road at about 9am. 'After examining the tyre marks left at the scene and the impact of the crash, government experts estimated that the speed of the coach was about 70km/h before it slammed into the noise barrier,' a police source said, adding that police said the speed limit at the site of the accident was 50km/h. 'Evidence we have obtained so far indicates that the coach did not slow down as it was running at the foot of the downhill section of New Hiram's Highway and driving into the roundabout,' the source said. Meanwhile, the Hospital Authority said 33 people remained in eight hospitals: six in critical condition, 12 serious and 15 stable, after the city's worst traffic accident in five years. The bus carrying 61 passengers was one of three taking members of religious group Shinji Shumeikai from Wong Tai Sin to its headquarters in Sai Kung. It ran out of control at the roundabout, flipped on its side and rammed into a noise barrier. The roof was crushed and seats twisted, trapping the dead and injured. Senior Superintendent Leung Fui, of Kowloon East traffic unit, promised to reinforce the anti-speeding message to drivers of heavy vehicles and buses to prevent traffic accidents on downhill sections of highways. He said speed checks were conducted frequently at the Nam Pin Wai roundabout, which he said was not a traffic black spot. In the first quarter of this year, 32 speed checks were conducted near the roundabout with 519 drivers prosecuted for speeding. 'Motorists should reduce speed and engage low gear near the roundabouts,' Mr Leung said after the first inter-departmental meeting on the accident yesterday. The meeting, jointly held by police and the transport, highways, social welfare and home affairs departments, will discuss measures on relief and road safety and report to the district council next week. Sai Kung district councillors at a meeting yesterday also urged investigations into potential dangers of other downhill roads in the district.
