Police were hunting for a minibus driver on Wednesday who they suspected hit and killed a road maintenance worker but drove away without stopping. Officers said they later found the vehicle at a repair yard in Yiu Sha Road, Ma On Shan, but the driver could not be located. “Preliminary findings indicate that [the accident] involved one minibus. The driver did not stop and had left the scene,” Senior Inspector Yung Pak-kuen of the Kowloon West traffic division special investigation team said. “There is some indication that there were passengers on board, so we hope any passengers who have information will get in touch with police.” The minibus was believed to have been travelling from Lion Rock Tunnel towards Kowloon when it knocked down the 42-year-old workman, surnamed Tam. It did not stop after the collision, police said. Work tools, a lacerated hard hat and fragments of a vehicle headlight lay scattered over the road. A large pool of blood marked the section of the flyover just opposite Baptist Hospital in Kowloon Tong where the accident occurred. The incident took place at around 1am as about four workmen were conducting road works on the section of Waterloo Road. The victim suffered heavy injuries and was sent unconscious to Queen Elizabeth Hospital. He was certified dead shortly after 3am. Signs were erected at the construction site and it is understood the workmen were wearing high-visibility reflective vests, Yung said. In a written response, the Highways Department confirmed that the workman was an employee of one of its contractors and said it was "saddened" and "concerned" about the incident. The crew was tasked with carrying out maintenance work on the roadway’s structural joints from 11pm to 5am on Thursday. It said the speed control was 50km/h and enough warning signs were erected.“There were warning signs, traffic cones and a construction truck parked at the site with light signals, to tell road users that the slow lane was closed because of construction [works],” a spokesman said. All contractors, the department added, are requested to make sure road safety measures such as proper lighting, signage and protective gear are in place at work sites to minimise potential hazard to workers and motorists. An investigation by Kowloon West officers is under way. Police asked anyone with information to contact the investigating officers on 3661 9000 or 3661 9062. In June, three road maintenance workers were killed on the Tsing Kwai Highway when a taxi crashed into a truck, which then hit them. They were collecting cones used to mark off an area for roadwork. On Wednesday, a driver was killed and two passengers injured when a minibus crashed into two parked road maintenance vehicles in Aberdeen.
