Authorities are searching for a 69-year-old man who disappeared last week after arriving at O'Hare International Airport on a flight from London.

Thomas Richardson was scheduled to board a flight to California but did not. Chicago police said in an alert that he has been forgetful recently and has gotten lost before.

He is described as 5 feet tall, weighting 210 pounds, with brown eyes, gray hair and a dark complexion. He was last seen wearing a brown- or caramel- colored suit, a beige shirt with a pin-striped diamond patter, black leather shoes and a navy jacket.

There is a slight bump on his forehead, according to the alert.

Anyone with information can contact Area North detectives at (312) 744-8200.
