A man has been charged with the murder of pub worker Iuliana Tudos, who was killed on Christmas Eve.
Kasim Lewis, 31, will appear at Wimbledon Magistrates' Court on Wednesday.
Lewis, of Friern Barnet, north London, was arrested by police at an address in Dalston, east London, at around 1.30pm on Monday.
Ms Tudos' body was found by a member of the public on 27 December in a disused building in Finsbury Park, near her home.
Police said Ms Tudos, a 22-year-old of Russian and Greek origin, was last seen by friends at around 8pm on Christmas Eve.
She had been heading for a bus home from Camden.
She was expected to meet the group at another friend's home in Enfield later that night, where she was also meant to spend Christmas Day. But she never arrived.
One of Iuliana's friends, Sonny Webb, told Sky News she was "like my little sister".
"She was a lovely person to be around, a caring person.

"She meant so much to me and the world is not going to be the same without her."
A post-mortem examination concluded Ms Tudos had died from a stab wound to the abdomen and a head injury.
