Family hold onto hope for missing swimmer THE family of missing NSW man Martin Tann, who has been missing since going for a swim in Perth, remain hopeful that he will be found alive. Police began scaling back the sea and land search for Mr Tann on Thursday after he went missing on Tuesday, and said the possibility of a shark attack could not be ruled out. But on Friday, police issued a joint statement from Mr Tann's family saying they would continue the search until all possible avenues were exhausted. "An extensive search and rescue operation continues to be conducted, however so far, no evidence has been recovered," police said. Marty is a friendly, outgoing and gregarious person. His family find it extremely difficult to think that he could disappear without a trace. Family and friends have flown interstate to help with the search, and remain confident Mr Tann will be found alive and well, police said. Mr Tann's clothes and belongings were found abandoned on a Perth beach on Tuesday. Anyone with information is asked to call Crime Stoppers on 1800 333 000.
