"In the past he has always been brought back the same day," he said. "This will be the fourth day he has been out in cold weather and he won't be in a good way.
"Every time we get a call we are nervous about what that might be."

"We would ask anyone who thinks they may have seen him to contact the police."
"The SubFootball league competitions used to be held at three main venues - the Domain, Walker Park (Pt Chevalier) and Seymour Park (Epsom)," he said.
"He may have been trying to get to one of these locations and may have encountered someone along the way and engaged them in a discussion about the sport he was passionate about.
"If so, we and the Police want to hear from whoever he spoke with or whoever might have seen him."
