Police have launched a murder investigation after a man was found stabbed to death and dumped near a brook in a busy park.
Detectives believe the body is that of Yassar Mustakim Moussa, 37, who lived in Walthamstow in north-east London and was last heard from on Saturday night.
He was found dead in St James Park in Walthamstow at about 1.40pm on Monday.
A post-mortem examination held on Tuesday found the official cause of death to be a stab wound to the neck.
As police trace Yassar's final movements leading up to his death, they want to hear from anyone who spotted vehicles near the park's entrances or any unusual activity in the park from Saturday night.

"Detectives are appealing for information and witnesses who may have noticed any vehicles hanging around the park entrances or any unusual activity in the park since Saturday evening.

"Officers attended and a man, aged in his thirties, was pronounced dead at the scene.
"While formal identification awaits, police are confident the deceased is Yassar Mustakim Moussa, 37, who lived in Walthamstow.
"His next of kin have been informed and are being supported by officers.
"A post-mortem examination held on Tuesday, 25 August found the official cause of death to be a stab wound to the neck."
The spokesperson added: "Detectives understand that Yassar was last heard from on the evening of Saturday, 22 August.
"Now detectives from the Met’s Specialist Crime North command are working to establish the circumstances of the events leading up to his death, and appealing for anyone with information to come forward and help them."
DCI Larry Smith, who is leading the investigation, said: “A man’s life has been brutally taken and his body left in a park.
"We need to know the movements of Yassar from Saturday, 22 August and my team will be working tirelessly to identify those involved.
"This is a busy park with lots of people using it and I’m asking those park visitors, and nearby residents, to really think back over this weekend.
"Did you see anything out of the ordinary? Did you see a vehicle drive in or out of the park through either the north or south gates?
“Someone out there knows what happened to Yassar and I’m asking you to do the decent thing and speak up. If you don’t want to talk to us, you can stay anonymous by talking to Crimestoppers.”
Acting North East Borough Commander Waheed Khan added: “My thoughts are with Yassar’s loved ones, who must be devastated not only by his death, but by the callous way in which he was treated.
“I know the local community will be shocked by these events, but please be assured that officers will do everything in their power to find who is responsible.
“Officers will be conducting increased patrols locally so residents can expect to see an additional police presence in the area. We are here for you so please do talk to our officers if you have any concerns.”
