Two kidnapped former businessmen were rescued by police from a village house in Sai Kung yesterday after being held for more than three days by captors seeking a $1.3 million ransom from their families. The men, aged 63 and 71, were found locked in a single-storey house in Hung Uk Village, Clear Water Bay Road, when officers wearing bulletproof vests and carrying shotguns broke in at 3am. Senior Superintendent Wong Fook-chuen, of Hong Kong Island regional crime unit, said: 'The two victims were not tied up but bruises were found on their bodies and they also suffered minor facial injuries. 'They had been punched and kicked in an apparent attempt to win their co-operation.' Police last night found two pistols in the house. Officers said no ransom was paid, although several calls had been made to the victims' families. Last night, the men returned to their homes in Wan Chai and Sha Tin after being treated in hospital. Police said they had run two separate trading companies before they retired. Four suspected kidnappers - three men and a woman - were arrested in the house. Another male suspect was arrested in a house about 100 metres away. It was the sixth kidnap case this year. There were four cases last year and four in 1999. Mr Wong said there was no indication the increase was linked to the economic situation. Two of the suspects told investigators the retired men owed them more than $1 million in a business dispute. The victims' ordeal began when the 63-year-old man was abducted during an appointment with two of the suspects, aged 39 and 50, on Friday. He was driven to the house in Sai Kung. Investigators said he was forced to call the other man and invite him to a Kowloon Tong restaurant on Saturday, where he was abducted. The wife of the 71-year-old man received a call on Sunday demanding $800,000. The live-in girlfriend of the 63-year-old victim received a call the same day demanding $500,000. The women called the police. The suspects were being held at Western police station.
