An elderly South Korean tourist has gone missing in London after becoming separated from her family while boarding Tube train.
Hoyeon Jang, 75, who does not speak English, was last seen on Thursday at around 5pm getting on a Northern Line train to High Barnet at Embankment station, in central London.
The doors closed before her husband and son could board and, although they signalled for her to get off when it next stopped at Charing Cross, they were unable to find her when they arrived.
They also searched Archway but after several hours reported her missing at 8.05pm, the Metropolitan Police said.
Ms Jang is described as 4ft 11ins tall, with short black hair, and she was last seen wearing a yellow jacket and blue trainers.
She is not in possession of a phone and has no access to money.
The Met appealed for sightings of the woman, saying they were "increasingly concerned" for her welfare.
