Tests on the decomposed body of a man pulled from the sea off the Kent coast have proved inconclusive.
An RNLI team recovered the body after it was spotted by the crew of a passing ship four miles (6.4km) from Whitstable on 27 May.
Kent Police said the results of a post-mortem examination were inconclusive and further tests would take place to help determine the cause of death.
The identity of the 6ft tall man is still unknown.
The ship was passing sandflats off Whitstable when the body was spotted at 1315 BST.
It was taken to the Queen Elizabeth The Queen Mother Hospital in Margate after being retrieved by the lifeboat crew.
