A man has been stabbed to death while out in West Ham Lane Recreation Ground in Stratford.
The 20-year-old, who has not been named by police, was attacked at about 3.15pm on Thursday, July 21.
Police and London’s Air Ambulance attended but the victim was pronounced dead at the scene.
Tony Cook, 29, told the Standard: “As I was going on the school run I could see the air ambulance above me looking to land. I also saw the faces of concerned police officers running at full pace to attend.
“On my way back from the school run, I could see loads of police officers patrolling the park and also escorting parkgoers safely out of the park. The emergency services looked to have everything under control.
“It’s a shame Newham has got like this. I’ve lived in Stratford all my life and when I was growing up it was a fist fight, no-one was killed, just a little battered.
“What is the world coming to? I don’t really want my two daughters growing up around here if I’m totally honest.”
Two male youths - aged 16 and 17 - were arrested nearby on suspicion of murder and have been taken into custody at an east London police station where they remain.
Detectives from the Homicide and Major Crime Command are investigating the murder and have appealed for witnesses and information.
Detective Chief Inspector Gary Holmes, who is leading the investigation, said: “It was a busy time of day when this violent incident has occurred and I am appealing to anyone who was in an around the area, and who may have witnesses the incident or saw or heard anything suspicious, to contact our incident room.”
Whilst detectives believe they know who the deceased is, formal identification awaits. Next of kin have been informed.
