A murder investigation has been launched by police following the discovery of a young woman's body in Finsbury Park.
The woman, aged 22, was named by Metropolitan police as Iuliana Tudos, and is understood to have worked at the World's End pub.
She was originally from Moscow.
She was pronounced dead at the scene after her body was discovered by a member of the public.
A crime scene remains in place and investigators have erected a tent in Finsbury Park.
The police investigation is being led by Detective Chief Inspector Nicola Wall.
She said: "Iuliana's body was discovered in an outbuilding next to a sports pitch. We believe that she may have been attacked on Saturday, 24 December – Christmas Eve – but we want to hear from anyone who saw anything suspicious in that part of Finsbury Park over the Christmas period.
"We are still trying to piece together a timeline of events and are pursuing a number of lines of enquiry as regards to a motive."
Ms Tudos was last seen by her friends around 8pm on 24 December when she headed for a bus home from Camden.
She was due to meet them at a friend's home in Enfield later that evening before spending Christmas Day there, but never arrived.
Ms Tudos was wearing a black and red hooded top with "Agnostic Front", an American punk band, written on it, with light jeans and black and white Vans shoes.
Her body was found in the park just before 4.30pm on Wednesday, near to a baseball pitch. It's understood she was close to her home, in Upper Tollington Park, which was searched by police.
Neighbour Sebastian Jonathan said: "She was a very nice person, young and gorgeous.
"I met her twice when she came over for beers when we had barbecues last summer."
