Detectives would like to speak to this man over the death of 28-year-old primary school teacher Sabina Nessa.
CCTV images have been released following the arrest of another man on suspicion of murder, in Lewisham, southeast London this afternoon.
Friends say Sabina was on her way to a pub before she was attacked in Cator Park, Kidbrooke, shortly after 8.30pm on Friday night.
It should have been a five minute walk from her home in Greenwich, southeast London, but she never made it.
Her body was found by a dog walker at 5.30pm the following day hidden under a pile of leaves.
Sabina’s friends described her as a ‘lovable person’ and a passionate teacher who someday wanted to travel to Dubai for work.
Paying tribute on social media, her sister said: ‘My beautiful talented & caring sister, my inspiration to always put myself first & never let anybody put me down never in my life did I or my sisters or my mum or dad think this could happen to us.
She added: ‘No mother or father should have to go through this, may Allah grant my parents ease.’
CCTV released by the Met shows the man officers are looking for walking in Pegler Square, in London’s SE3 area, on the evening Sabina was attacked.
Detectives have also released an image of a silver vehicle they believe the man has access to, which was also captured in the same area.
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.’
A post-mortem examination carried out on Monday was inconclusive.
Anyone with information should call the incident room on 0208 721 4266 or Crimestoppers completely anonymously on 0800 555 111.
