A worried dad is urging the public to help find his vulnerable missing son.

Tony Dickinson, 31, who has only one eye, has not been seen since leaving his mother’s home in Westburn Crescent, Keighley , at 10am on Wednesday to go for a walk.

His father Patrick, 58, of Bradford, yesterday said he was worried about the welfare of his son, who lost an eye through retina blastoma when he was two. Police are also appealing for help to trace Mr Dickinson.

The alarm was raised at about 10.40pm on Wednesday and family and police are becoming increasingly concerned for his welfare.

His father said: “It is totally out of character for him to disappear like this without saying a word to anyone. I would have expected him to have told his mother, who he lives with.”

Mr Dickinson said his concern was heightened by the fact that his son had left a one-word entry on his Facebook site – “Bye,” and that calls to his mobile phone were going to his voice mail.

But since his disappearance money had been withdrawn from his bank account from a cash machine in Leeds and police were now concentrating their search for him in that city.

Mr Dickinson said: “He is on holiday from work, a financial institution in Skipton , this week and it may simply be that he has decided to go off somewhere where his mobile does not work.

“But it is completely out of character and I can’t emphasise too much how worried I am about him.”

Mr Dickinson said he was last in contact with his son about a month ago about going to see a film, when he had been cheerful and normal.

Tony is described as white, 5ft 10ins tall and of large build, with short darkish hair and a glass eye. He was wearing light blue jeans, a maroon-coloured shirt and leather-effect bomber jacket.

He may have slightly slurred speech due to a medical condition and is believed to travel around West Yorkshire and occasionally into the Skipton area.

Anyone who has seen Mr Dickinson or has information about his whereabouts is asked to contact Airedale and North Bradford CID on 101 or Crimestoppers, in confidence, on 0800 555 111.
