A 72-year-old man was arrested on suspicion of stealing a bank book for an account containing about HK$9,000, HK$500 in cash, a signature chop and a mobile phone from an 82-year-old friend he found dead in Hung Hom yesterday.
The suspect found Kwan Yuk-wah's body when he visited his friend's Lai Man House flat in Oi Man Estate at about 9am.
Kwan, a retired security guard, was found on the floor beside his bed. Police said he had given a key to his friend in case he died and no one discovered the body. Kwan was declared dead at the scene by an ambulance crew.
A police spokesman said an autopsy would be carried out today. Kwan had lung cancer and asthma.
Police became suspicious when Kwan's friend was found to have money hidden in one of his socks.
The money and other items were seized and the man, a retired butcher, arrested.
He had known Kwan for 20 years and the pair regularly met for dim-sum breakfasts. They last had breakfast together on Sunday.
It was a case of a good person being overcome by greed, a police source said. The man was being held at Hung Hom police station last night for questioning.
