Police and SES crews are searching the banks of a creek in far north Queensland after a man disappeared while swimming.
Selwyn Malayta, 48, was last seen by another man when the pair went for a swim in Plantation Creek, in Ayr, about 1.30am on Wednesday.
The second man returned to the creek bank first and called out to Mr Malayta, but there was no response.
Police and SES personnel are combing the creek for any sign of the missing man.
They have urged anyone who has seen Mr Malayta to contact police immediately.
