A father of two killed yesterday when his van ploughed into the back of a street-sweeping truck was exhausted after working virtually round the clock to pay off his family's debts, his widow said. Fu Chi-hung's delivery van hit the Urban Services Department truck on a slip road in Yau Ma Tei shortly after 4.30am. Fu, 32, who was delivering noodles to shops in Kowloon, was driving on to the West Kowloon Corridor from Ferry Street, when he collided with the slow-moving truck, police said. He was trapped in the wreckage and had to be freed by firefighters but was declared dead at Kwong Wah Hospital nearly six hours later. Fu, whose electrical and drainage sub-contracting business collapsed leaving him in debt, is survived by his widow, 30, daughter, 12, and son, three. His widow said she suspected the accident was caused by tiredness as she said he had not slept properly for months. She said he was the family's breadwinner and had been forced to take three jobs to make ends meet. Her husband earned between $20,000 and $30,000 a month but most of this was used to settle debts and pay $5,000 rent each month, she said. He left home each day at about 8am and went to work on a construction site, returning home at about 6pm, said the woman, who asked not to be named. Four hours later he began rubbish collection work in Sha Tin and at 3am began delivering noodles until dawn.
