A woman and three men arrested over a fatal stabbing in east London have all been bailed or released under investigation.
A man believed to be in his 30s died on Wednesday after being stabbed in Matthias Road in Stoke Newington.
A 33-year-old woman and three men, aged 57, 58 and 62 were arrested on Thursday on suspicion of murder, police said.
On Friday, the 62-year-old man was bailed to a date in the middle of May.
The other three were released under investigation.
Police were called to the scene at about 5.47pm and started administering CPR but the victim was pronounced dead at 6.10pm.
Officers believe he may have been attacked in nearby Cowper Road and crime scenes are in place in both locations.
The deceased man’s next of kin have been informed.
Detective Chief Inspector Paul Considine of the Metropolitan Police said: “This attack took place in the early evening, in a residential street and in broad daylight. There would have been people around and I need those people to call police.
“Whatever you saw, whether the fatal assault, the events leading up to it or the aftermath, it is vitally important that you call us. It is only by people working with police that we can make London safe and your call may be vital in helping us understand how a young man came to be brutally killed.”
