New York Life agent was industry's fourth victim in past eight months An insurance company executive was knocked unconscious in an apparent ambush by two men in a car park in Causeway Bay yesterday. It was the fourth attack on an insurance agent in eight months. The International Professional Consultants Association has expressed concern at the violence, saying it could be prompted by poor conduct by aggressive insurance agents. Its chairman, Paul Law Siu-hung, said some insurance agents might have made exaggerated claims about insurance policies to their clients because of the fierce competition in the industry. 'Insurance agents should follow the guidelines and outline the pros and cons to clients. They should also tell customers the advantages as well as the possible risks that their clients may suffer,' he said. Wu Kin-wing, 44, of New York Life Insurance, was attacked after parking his Mercedes-Benz in the car park on the second floor of Windsor House in Gloucester Road just before 9am. Mr Wu, who is also one of three vice-presidents of the General Agents and Managers Association of Hong Kong, was on his way to work at the time of the attack. His office is in Windsor House. He was found lying unconscious on the ground by a colleague about five minutes later. Mr Wu, who was bleeding from his head, returned to a semi-conscious state before being put into an ambulance. He was taken to Queen Mary Hospital, where he was in stable condition last night. Footage from surveillance cameras at the car park showed that he was attacked by two men, police said. 'As the victim was opening his boot to collect something, the two male assailants appeared,' a police spokeswoman said. 'One of the two culprits acted as a lookout and the other, wearing a black cap, approached the victim from behind and clubbed him with an unknown hard object.' The men did not steal anything or search Mr Wu before fleeing. Officers searched for the men but no one was arrested. Mr Wu told investigators that he had no debt problems and he did not know why he was attacked. 'It appeared to be an ambush. It was apparently a warning rather than an attempt to kill him. Otherwise the victim would not have suffered minor injuries,' a police investigator said. 'The victim told us that he had not received any warning or been involved in any dispute with anyone.' A statement issued by Mr Wu's company said: 'The police are investigating this attack and we are helping the police as much as we can with their inquiries. 'We do not know why this attack took place and have no further comment at this time.' On February 23, Joe Cheng Kwok-shing, 49, a general manager at the Shenzhen branch of American International Assurance (AIA), was shot at a restaurant in Causeway Bay during an apparent robbery. Mr Cheng is understood to have been placed under police protection and is still recovering in hospital. No one has been arrested in connection with the case. In August last year, the charred body of Chu Ka-shum, 44, who was also an AIA staff member, was found in a suitcase inside a container in Yuen Long after the container burst into flames. Also in August last year, another insurance agent, Lee Kwok-sum, 39, had his right hand hacked off by two attackers at a restaurant in Mongkok.
