In what is being described as "significant development", the Metropolitan police have confirmed that a 36-year-old man has been arrested in the early hours of Sunday, Sept.26 morning on suspicion of murdering a primary school teacher.

On Sept.17, the now-deceased teacher, Sabina Nessa had been walking near the Cator Park, in Kidbrooke Park Road, south-east London, to meet a friend at a pub when she was reportedly attacked.

The following day, a member of the public discovered the 28-year-old’s body hidden under a pile of leaves.

During a preliminary investigation, the Met police separately arrested two men on suspicion of her murder but were subsequently released under investigation pending further enquiries.

Leading the investigation, Detective Chief Inspector Joe Garrity from the Specialist Crime Command said: "Our initial enquiries suggest that this attack happened at around 20:30hrs on Friday, 17 September, a time when the park was likely being used by many people from dog walkers to joggers."

"Sabina was found near the OneSpace community centre which we know is a facility used by lots of people and we would ask anyone who was in or around the area and who may have any information to come forward."

"We are working around the clock to deliver justice for the family of this young woman, and we need your help to do it," the officer had said earlier.

On Sunday morning, the police announced they have taken an unidentified man into custody on suspicion of murdering Nessa, a Cambridge-educated primary school teacher

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."

The Met had previously released CCTV footage showing an unidentified man they wished to speak to in their enquiries.

However, it is unclear at this time whether the man arrested on Sunday is the same man featured in the CCTV footage.

DCI John had said: "Please share the CCTV footage on social media and, especially if you have connections to London or Kent."

"Show the image to family members and friends who may not have seen it. He must be traced."

"We all saw at yesterday evening’s vigil, the impact that Sabina’s death has had on the community."

"I would reiterate my plea to those in the local area to think and if you have any information that could help this investigation, then please get in touch."

The OneSpace centre, a community centre near to where she lived, have opened up a book of condolences for visitors to write messages to remember the ‘brilliant’ teacher.

One read: "Please know that we are here, we will continue to stand with you in solidarity, as a community, as mums, fathers, sisters, cousins, aunts and grandparents."
