A Russian tourist has been missing for two days after getting lost on the London Underground.
Vasile Belea, 63, was last seen at Stockwell Tube station in south London at 10am on Tuesday.
His son boarded a Victoria line train towards central London but the doors closed before his father could join him.
Police believe Mr Belea might have got on the following train or tried to return to Hackbridge, Sutton, where he had been staying at his son's home since just before Christmas.
He is due to return to Russia at the end of January. Mr Belea is 6ft tall with grey hair, and he was wearing blue jeans, a long black jacket and a black flat cap.
He has money and an Oyster card but was not carrying any medication for his arthritis. He has a mobile phone but it has no sim card.
Anyone who has seen Mr Belea is urged to call 999.
