The Hong Kong government is helping the family of a businessman from the city shot dead by robbers at his home in South Africa. Lau Heung-wing was shot five times in the raid. Five robbers broke into the 39-year-old's home in a suburb of Johannesburg on Tuesday evening. Lau tried to resist the robbers, opening fire with his own gun and killing one of the intruders. But in the shootout, he received bullet wounds to his face, chest, shoulder and arm, Xinhua reported. He died in the early hours of the following morning. Staff from the Chinese embassy in Pretoria visited the scene of the shooting and said they would work with South African police on the case. A neighbour who tried to rescue Lau blamed medical staff for refusing to help on the grounds he lacked medical insurance and they had no cash on hand. He said Lau was sent to a hospital nearby and his bullet wounds were not cleaned during the first three hours he was there. In Hong Kong yesterday, an Immigration Department spokesman said: 'We just received a request for help from the victim's family and we will co-ordinate with the Chinese embassy.'
