A South Korean tourist who went missing in London has been found "safe and well", police have said.
Hoyeon Jang, 75, was separated from her husband and son when she boarded a Northern Line train without them at Embankment station on Thursday.
They signalled to her to get off at Charing Cross, the next station, but could not find her there or at Archway station, where they were going.
The Met Police said Mrs Jang was found on Saturday afternoon.
Officers previously said Mrs Jang was last seen at Embankment station at about 17:00 BST on Thursday and was reported missing to the force about three hours later.
The family had been visiting relatives in London.
