A senior employee at the Wen Wei Po newspaper died yesterday, two days after a mystery attack when he returned to Hong Kong following a mainland business trip. Yu Sze-ching, the 44-year-old head of the paper's information technology department, suffered serious head injuries and was found in Shek Kong Airfield Road outside Tai Kong Po Tsuen, Pat Heung, on Thursday night. His head had been bludgeoned, tape was wrapped round his injuries and his hands and legs were tied with nylon string. The father of two was in a coma when he was taken to North District Hospital, where he was certified dead at 12.13pm yesterday. The Hong Kong Federation of Journalists expressed shock over the loss of a long-time member. It sent condolences to Yu's family. Police said Yu was waylaid in a car park in San Wan Road outside Sheung Shui KCR station on his way back to the territory from Shenzhen. His jacket and wallet, containing $1,000 and credit cards, were found beside his vehicle in the car park on Friday. Police said the motive for the attack was still unknown and the Yuen Long District Crime Squad was investigating.
