POLICE have recovered CCTV of a man attacking Sabina Nessa shortly after she left her apartment, it is understood.
Sabina, 28, was found hidden under a pile of leaves by a dog walker in Kidbrooke, southeast London on Saturday.
The poor quality film is said to show her being struck over the head with a large weapon.
A police source told the Daily Telegraph that Sabina was then carried away over the attacker’s shoulder towards Cator Park.
A post-mortem examination proved inconclusive over her cause of death.
A 38-year-old man is currently being held on suspicion of murdering the 28-year-old teacher.
The Metropolitan Police have issued CCTV images of a man walking in Pegler Square, Kidbrooke, on the evening she was attacked.
They have also released an image of a silver vehicle they believe he has access to.
Detectives understand that Sabina left her home on Astell Road, at around 8.30pm last Friday.
Reports suggest that she was making her way through Cator Park towards The Depot bar on Pegler Square, Kidbrooke Village where she planned to meet a friend.
Sabina never arrived at the pub and is thought to have been murdered as she walked through the park, around five minutes from her home.
Detective Chief Inspector Neil John 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.”
It comes as it emerged tragic Sabina was “excited” about going on a first date with an old pal before she was murdered.
A friend told The Sun: “She was a loveable person, she loved kids. She just wanted to live her life.
“She had many plans. She wanted to go to Dubai and teach children there.
“She was very excited. But not nervous. She was happy about seeing him.”
Another friend near her flat added: “She was looking forward to it a lot. This is so tragic. It’s awful.
“She was the nicest woman in the world. It’s left us all heartbroken.”
The journey should have taken her five minutes, but Sabina never arrived and cops believe she was murdered as she walked through the park.
Sabina was not reported missing by anyone after failing to show up to the bar, and her body was not discovered until 5.30pm the next day, September 18.
But officers have now expressed a concern that another attack by her killer, who they believe was a stranger, “could” take place.
Detective Chief Superintendent Trevor Lawry has said: “It’s always a concern that it may happen, but that’s not something that we have any intelligence on at this time.”
When asked whether he believes a stranger was behind the attack, he added: “That’s definitely a line of inquiry that we’re looking at.”
Speaking from the crime scene in Cator Park, Kidbrooke, he added detectives are “keeping a completely open mind” on what the motive of the attacker may have been.
He confirmed that there were “significant” lines of enquiry when asked whether police have any leads on who the killer may be.
DCS Lawry also insisted that London’s “streets are safe for women” following the murder of the primary school teacher.
The Met’s Detective Inspector Joe Garrity, who is leading the murder investigation, believes there are “still others out there who may have information” that could help.
He said: “If you think you saw Sabina or any suspicious behaviour in or around the park on Friday evening please speak to us.
“Sabina’s journey should have taken just over five minutes but she never made it to her destination.
“We know the community are rightly shocked by this murder – as are we – and we are using every resource available to us to find the individual responsible.”
A post-mortem examination carried out at Greenwich Mortuary on Monday, September 20 was inconclusive.
Her cousin Zubel Ahmed told ITV News yesterday: “She was due to go and see her family at the weekend and even that… she couldn’t even do that one last time, unfortunately.”
The shock has not sunk in. She was a beautiful, kind, caring soul.
Zubel paid tribute to his cousin and described her as the “sweetest person” saying that the devastated family do not understand how “someone can do this”.
Zubel added: “We went and saw her parents, they are inconsolable. It’s the worst way for someone to go.
“The shock has not sunk in. She was a beautiful, kind, caring soul.
“I express my deepest sympathies for her sisters – Mum and dad are absolutely devastated.
“Nothing is making sense to us, why was she taken from us we just don’t know.”
Sabina’s death has sparked outrage after she joined a growing list of women killed in public spaces in London in recent months.
Campaigners are now demanding action to tackle violence against women in the wake of the latest tragedy.
Our Streets Now said: “It’s why we don’t walk where we want when we want.
“It’s why we tense at the sound of a car pulling up, or of a man crossing the street towards us.
“It’s why one in five girls have avoided their place of education. Please, stop telling us we’re overreacting.
“Sabina Ness, Sarah Everard, Bibaa Henry, Nicole Smallman. And these are just the names that we remember.
“Male violence is killing us. It’s restricting our right to be free and equal citizens. We need change, now.”
