Christchurch police are no longer treating the death of a man whose body was found in the Heathcote river as suspicious.
The body of a man aged about 20 was found at about 9am on Saturday by a woman walking in the Beckenham area.
Initially police had thought the man may have been the victim of foul play, however a post mortem conducted on Saturday afternoon concluded that he had drowned.
Police believe he died sometime after walking home from a party on Centaurus Avenue between 1am and 2am on Saturday.
The matter is now being referred to the coroner.
Police are not releasing the man's name until all next of kin have been informed.
