Authorities are continuing to investigate the murder of primary school teacher, Sabina Nessa, almost a week after her body was found.
The 28-year-old, who has been described as the "kindest, sweetest girl you could meet", was attacked as she walked to meet a friend close to her home in southeast London, on Friday, September 17.
On Thursday, September 23, police announced that a second individual had been arrested on suspicion of murder — after the first was released following further investigation.
Here is everything we know so far.
What happened to Sabina Nessa?
Sabina Nessa left her home in Kidbrooke at 8:30 PM on September 17 to meet a friend at a nearby pub called The Depot Bar.
Her journey — which should have taken just five minutes — would have lead her through Cator Park, which was being used "lightly" by runners and dog walkers.
However, the 28-year-old never arrived, and her body was discovered under a pile of leaves by a passerby the following afternoon.
On September 20, police formally identified the remains as belonging to the teacher, but a post-mortem examination carried out at Greenwich Mortuary was deemed "inconclusive".
On Tuesday, September 21, The Metropolitan Police revealed that Ms Nessa's body was not found until several hours after her death. There was a "small delay" in finding her remains, because it was not in the "main walkway" of Cator Park, said Detective Superintendent Luke Marks.
"A member of the public found the body the morning after the attack," he added.
On September 23, The Telegraph reported that she was attacked just moments after she left her home by a man who struck her on the head with an unidentified object, per a police source.
The CCTV footage shows him carrying her over his shoulder towards the public park, where she was found almost a day later.
About Sabina Nessa
Ms Nessa was a year one teacher at Rushney Green Primary School in Catford, where she had worked for just over a year.
The 28-year-old was described as a "brilliant teacher" by headteacher, Lisa Williams.
Speaking about the incident, Williams stated, "We are devastated by Sabina’s tragic death. She was kind, caring, and absolutely dedicated to her pupils. She had so much life ahead of her and so much more to give."
Law enforcement has said that Ms Nessa — who lived in Kidbrooke, south east London — was unmarried and had no children.
Her cousin, Zubel Ahmed, told the BBC that she was the "kindest, sweetest girl you could meet."
"We’re still in shock. It’s been a few days but it’s still not sunk in yet," he continued, adding that her parents are "inconsolable."
"We are all truly devastated. Her parents are absolutely shocked, they’re inconsolable still and understandably so, to hear of their daughter being taken away from them by some cowardly man is just horrific. She honestly was the most caring person, kindest, sweetest girl you could meet. Sabina’s heart was as good as gold, she never had a bad word to say about anyone. Her sister is going to miss her so much.
"She’s just got a beautiful soul she’s a caring person. She’s left behind two cats, when we were at her house the other day the cats were looking for her. She’s just going to be truly missed. I just can’t find the words to express my sadness at this time."
Her sister, who uses the Twitter handle, @jaxjn02, took to Twitter to pay tribute to Ms Nessa, who she said was her "inspiration".
"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 [sic]," she wrote. "3 sisters down to 2. No mother or father should have to go through this, may Allah grant my parents ease."
Has anyone been arrested?
On Saturday, September 18, police arrested a man, who was said to be in his forties, on suspicion of murder. He was ultimately released after further investigations were conducted.
On Thursday, September 23, Metropolitan Police arrested a 38-year-0ld man on suspicion of murder. The individual was arrested at an address in Lewisham, southeast London, and is currently in custody.
Law enforcement has also released CCTV surveillance images of a man they want to speak to. The photos show him walking in Pegler Square, close to Cator Park, on the evening that Ms Nessa went missing.
They also shared an image of a silver car, which they believe he has access to. Anyone who has any information on the man or the vehicle is being urged to contact the police.
On September 24, the force released footage of the individual, who can be seen looking over his shoulder and raising his hood.
"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," detective chief inspector from the Met’s specialist crime command, Neil John, said in a statement.
Fear for women's safety on the streets
Ms Nessa's death comes just six months after the kidnap and murder of 33-year-old marketing executive, Sarah Everard. Her death — at the hands of Met Police officer Wayne Couzens — sparked mass demonstrations over women's safety in public spaces.
Understandably, many feel like little has changed, as the country grapples with what has been deemed an epidemic of male violence against women and girls.
Feminist direct action group, Sisters Uncut, paid tribute to Ms Nessa on Twitter, writing: "Another day in the UK, another woman murdered at the hands of a violent man. Sabina Nessa was walking home when she was killed and her body left in a public place. Sabina’s story is harrowing and heartbreaking, our love and rage goes out to her family and loved ones. We refuse to be trapped in this cycle of grief and we will not rest until women and non-binary people are safe and unafraid!"
Meanwhile, Our Streets Now, which is committed to ending sexual harassment in public, said in a statement: "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 1 in 5 girls have avoided their place of education. Please, stop telling us we’re overreacting. Sabina Nessa, 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."
On September 24, campaign group, Reclaim These Streets, is holding a vigil for Ms Nessa.
"On Friday night, we will join Sabina Nessa’s community in solidarity against violence against women and to acknowledge her life. Join us in Peglar Square at 7pm. If you can't join in person, please light a candle at 7pm on your doorstep," they tweeted.
