THE 17-year-old youth who was trampled during an Andy Lau Tak-wah concert at the Hongkong Coliseum nine days ago died at about 10 o'clock last night. Lee Kar-cheong was found unconscious below a staircase after fans stampeded in a chase for more than 1,500 balloons released from the ceiling. An older brother reported seeing Kar-cheong being pushed to the ground. He later fell into a coma. Kar-cheong suffered severe concussion in the melee, sparking further crowd control fears in the wake of the Lan Kwai Fong tragedy. Mr Justice Bokhary, the head of the independent inquiry into the New Year tragedy, said last night he would seek more information on the incident. His final report on Lan Kwai Fong is expected to be handed to the Governor, Mr Chris Patten, tommorrow. Urban Services Department manager Miss Ng Hang-bing said after the accident that no more balloon drops would be allowed as special effects for Lau's show until an internal investigation by the management of the Coliseum has been completed. Miss Ng said Andy Lau reminded the audience at the beginning of concert to stay calm and mind the steps when approaching the stage. The last of Lau's series of concerts goes on tonight. Mr Justice Bokhary had said it was difficult to determine from the limited information if the fall was related to crowd control, but he promised to look into it.
