Detectives investigating the murder of Sabina Nessa have arrested a 38-year-old man on suspicion of murder in what Scotland Yard said was a “significant development”.

Met Police announced the arrest on Sunday morning, just over a week after the primary school teacher was found dead in a south London park.

The force said he was arrested at around 3am on Sunday in East Sussex.

Detective Chief Inspector Neil John, from the Met's Specialist Crime Command, said: "Sabina's family have been informed of this significant development and they continue to be supported by specialist officers."

Sabina, 28, was killed as she set off to take what should have been a five-minute walk from her Kidbrooke home to meet a friend at a pub.

Her body found under a pile of leaves off a footpath in Cator Park, in the borough of Greenwich.

The death has caused an outpouring of public grief amid concerns for women's safety.

Her family spoke of their grief at the loss of the beloved young women as a vigil was held in the park where she was found.

On Thursday evening, investigators released CCTV images of a man they urgently wished to speak to, and one of a silver car they believed he had access to.

It is unclear if the man they sought is the man arrested.

The balding man was pictured walking in an area of Pegler Square.

The Met declined to speculate about the appearance of his hands in the images.

Ms Nessa had been walking to meet a date at a pub near her home when she was attacked during some point on her route on Friday, September 17.

Her body was discovered by a dog walker the next day.

Two men were separately arrested on suspicion of her murder but were subsequently released under investigation.
