Police are searching for a missing man believed to suffer from autism.

Roberto Correia, a 38-year-old Portuguese man who lives in Crawley, was last seen by his family at 8.50am on Thursday, May 22. 

A Sussex Police statement said he is very enthusiastic about visiting museums, especially in London, and was found in Liverpool when he went missing once before.

PC Matt Gowin said: "Roberto was seen to leave his home in Weald Drive on a bicycle at about 9.30am by some men working locally.

"He is not believed to have had much money and does not have credit or debit cards, so there is a fear that he is probably sleeping rough. Lately, he has become very interested in cruise ships and we would especially ask anyone living along the coast and near to ports to be looking out for him.

"Along with his family and friends, we are growing increasingly worried about his whereabouts and his health and if anyone has any information about him, please call Sussex Police on 101 quoting serial 766 of 22/05. If he is unwell or in danger, please dial 999 immediately."

Roberto is described as white with a tanned complexion, 6ft 2in, of medium build with short shaven black hair. He may be wearing blue jeans or grey jogging bottoms, a grey Adidas hooded top with red stripes on the sleeves and white Adidas trainers with green detail. His bicycle is a distinctive black and bright orange Carrera mountain bike.
