A police search for missing Coolangatta man, Michael Lalos (Lalopoulos), continues as the 84 year old has not been seen since he disappeared one week ago.

A Coolangatta police officer told Neos Kosmos there have been no sightings or news of the man since his disappearance on July 16, despite ongoing search efforts by family and police.

Lalos, who is originally from Melbourne, left his Coolangatta Road home just before 9am Thursday July 15 and was last seen walking in the vicinity of Centro Tweed later in the morning.

Police are concerned for the wellbeing of Mr Lalos as he suffers from medical conditions and may become easily disorientated. He was not in possession of his medication and was believed to be travelling on foot, police said.

Michael Lalos’ brother Nick Lalos-who lives in Melbourne- told Neos Kosmos that he was very concerned for his brother and found the situation puzzling.

“What can I say, it seems strange to me, Coolangatta is not a huge city, I don’t understand, how can no one have seen him yet?” he said.

Nick said his brother had gone out on the morning of July 15, withdrawn $200 from the bank, met friends at a cafe and was last seen buying a new strap for his watch.

“From that point on, once he left the shopping centre no one has seen him,” he said, adding that many people knew Michael Lalos and had seen him leave the watch-makers at the shopping centre.

Nick and his wife travelled to Queensland earlier this week, while his wife is still there continuing with the search.

“We put photos up everywhere, on the Internet, on local TV and radio, and in the local paper,” Nick said.

Mr Lalos was wearing a brown shirt, brown shorts and black thongs. He is described as being European in appearance, 170cm tall, of medium build with blue eyes and short white hair.
