Qld swimmer missing for almost a week

A homeless man hasn't been seen since he ran into waters off Queensland's Sunshine Coast to avoid arrest almost a week ago.

Officers were trying to arrest Ricky Gardner, 37, when he ran into the water and began swimming away from the shore at Noosa in the early hours of Saturday.

Police believe he may have fled because he was wanted on a return to prison warrant.

Despite officers carrying out an extensive search, Mr Gardiner hasn't been seen since Saturday and he hasn't contacted friends or family.

He has been described as Caucasian, about 178cm tall, with a slim build and light complexion.
