Police are investigating after a worker fell to his death following a dispute at a Tseung Kwan O construction site yesterday. Police said the 25-year-old man, surnamed Shek, was working on the 28th floor of tower one at Cheung Kong's Dream City on Wan O Road, when he fell to the podium on the first floor at about 1.30pm. He was declared dead at Tseung Kwan O Hospital at 1.55pm. According to police, Shek and another worker had a row, followed by a chase on the 28th floor, shortly before the incident. That worker was not identified and no arrest had been made last night.
