Police were called at 7.40am on Thursday, 25 January to reports of an unresponsive man at Hanworth Park.
Officers attended. At the scene the body of 19-year-old Tyler Donnelly was found. He had been stabbed and assaulted.
On Sunday, 28 January, three men, aged 21, 27 and 32, were arrested at different locations in London. They have been taken into custody.
A crime scene at the park has now been closed.
Detective Chief Inspector Brian Howie, leading the investigation from the Met’s Homicide Command said: “Tyler left his home around 9.10pm on Wednesday evening and rode his bike along Elmwood Avenue and at some stage entered the park. He never returned home.
“If you were in the park and saw something, regardless of the reason you were there, please get in touch. Our focus is on what happened to Tyler and who was responsible.
“Similarly, if you were driving through Elmwood Avenue, returning home or out walking, did you notice anything? Did you see anyone else in the park on bikes alone or in a group? Did you perhaps see Tyler, who was wearing dark clothing, riding his grey bike?
“The H25 bus route goes through Elmwood Avenue, were you travelling through this area on Wednesday or in the early hours of Thursday? Did you see Tyler or anyone matching his description?
“Tyler’s family and friends are inconsolable after receiving the worst possible news imaginable – our thoughts are with them and they are being supported by specialist officers.”
