Police have launched an urgent appeal to find a “vulnerable” man from Canada who is missing in London.
Khaled Omeed, 30, became separated from his family on the Jubilee Line platform of Baker Street Tube station at around 6pm on Friday and has not been seen since.
He had been visiting London with his family since July 10, staying in Hounslow.
Police said they were especially concerned because Khaled has a learning disability and is non-verbal. He is not familiar with London.
The family, who live in Toronto, were due to fly home on Saturday, but have remained in the capital as efforts to locate Khaled continue.
Anyone who may have seen Khaled is being asked to call 101, quoting reference 672/13Jul.
For an immediate sighting, officers ask that you dial 999.
