Search resumes for missing Brisbane man after unmanned boat found

The search for missing 26-year-old Brisbane man Trent Riley, who might have fallen off a boat in Moreton Bay, has resumed.

Police found a small aluminium boat driving uncontrolled off Mud Island, near the Port of Brisbane, about 3.30pm on Wednesday.

However, no one was found on board.

It is believed Mr Riley was wearing a long-sleeved grey fishing shirt, black jeans, black shoes and a bucket hat.

He is described as Caucasian, about 183 centimetres tall, of proportionate build, with a fair complexion and brown hair.

An aerial and sea search using 10 vessels and three helicopters, involving Water Police, Volunteer Marine Rescue and the coast guard, continued into the night for the 26-year-old.

The search continues.
