A Hong Kong businessman says he is heartbroken after burglars stole a safe containing antique samurai swords estimated to be worth $1 million from his home. Tong Kwok-kwong, 47, said the six swords, which he had collected about 10 years ago, were more than 300 years old. 'I am heartbroken that they have been stolen,' he said after the theft at his house in Sheung Sze Wan Road, Sai Kung, on Wednesday night. 'I like to collect samurai swords because they are a symbol of manliness.' Also in the safe were a hunting rifle and about 100 rounds of ammunition, and $100,000 worth of jewellery, he said. Mr Tong, who owns a jewellery factory on the mainland and has an office in Hong Kong, said he was licensed to keep the rifle and ammunition at home. The safe was stolen when Mr Tong's family were dining out. Police inquiries are continuing.
