The Honolulu Medical Examiner's Office identified a 61-year-old man who apparently drowned while swimming in the ocean off Waikiki as Kuang Cheng Pu of China.

Pu was swimming yesterday with other people about 100 yards from shore, fronting Hilton Hawaiian Village when he ran into trouble, authorities said.

He was brought ashore about 1:30 p.m. and taken to the hospital where he died.

An autopsy to determine the cause of death will be completed tomorrow.
