A 38-year-old man has been arrested on suspicion of the murder of teacher Sabina Nessa, the Metropolitan Police said.

Ms Nessa, 28, is suspected to have been murdered as she walked in south-east London, on what should have been a five-minute journey to a pub from her home, at around 8.30pm last Friday.

The Metropolitan Police said the man held by detectives investigating the murder of Sabina Nessa was arrested at an address in Lewisham, south east London and remains in custody.

The force have also released CCTV images of a man they wish to speak to, which show him walking in Pegler Square on the evening Ms Nessa was attacked.

It has also released an image of a silver vehicle captured in the Pegler Square area which detectives believe the man has access to, and urged anyone who recognises him or the vehicle to contact the force immediately.

Detective Chief Inspector Neil John, from the Met’s Specialist Crime Command, said: “Our team have been working tirelessly to find the person responsible for Sabina’s murder and this has included an extensive trawl of CCTV, work which remains ongoing.

“We would ask anyone – especially those in Kidbrooke and the wider area of Lewisham and Greenwich – to take a careful look at these images to check whether you know who this man is or have seen him over recent days.

“Any information as to his identity or whereabouts could be vital for our investigation so we are asking you to share this image far and wide to ensure as many people as possible see it.”
