A 38-year-old man has been arrested on suspicion of the murder of the primary school teacher Sabina Nessa, the Metropolitan police said, as detectives also released images of a man they wish to speak to. The 28-year-old is suspected to have been killed as she walked through Cator Park in south-east London, on what should have been a five-minute journey to a pub from her nearby home, at about 8.30pm last Friday. Her body was found in the park the following day. The Metropolitan police said the man was arrested at an address in Lewisham, south-east London, and remains in custody. Detectives have also released CCTV stills of a vehicle they are searching for. The images of the man, taken from CCTV, show him walking in Pegler Square, in the SE3 area of London, on the evening Nessa was attacked. Police released an image of a silver vehicle they believe the man has access to, which was also captured in the Pegler Square area. The Met is urging anyone who recognises the man and vehicle to make contact immediately. DCI 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.” A man in his 40s who was previously arrested on suspicion of murder has been released under further investigation. The community of Kidbrooke have organised a candlelit vigil at 7pm on Friday evening in Pegler Square to remember Nessa.
