A member of the public found the body of a man near a brook in St James Park at around 1.40pm on Monday, 24 August.
Detectives believe the victim is Yassar Mustakim Moussa, 37, from Walthamstow.
A post-mortem examination has given his cause of death as a knife wound to the neck.
Yassar was last heard from on Saturday, 22 August and detectives are investigating the events leading up to his death.
Anyone who noticed any vehicles hanging around the park entrances or any unusual activity in the park since Saturday evening is asked to contact them.
“A man’s life has been brutally taken and his body left in a park,” said DCI Larry Smith, who is leading the investigation.
“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 Khansaid: “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.”
No arrests have been made and enquiries continue.
Anyone who has information that could assist police with their investigation is asked to call 101 or tweet @MetCC ref CAD 3562/24 Aug.
