Almost a week on from the murder of a man in Islington, detectives are continuing with their appeal for witnesses and information.
From 23:00hrs on Friday, 3 March, detectives from the Homicide and Major Crime Command will be in and around the Upper Street area in the hope of speaking to anyone who was there last Saturday who may have witnessed the murder of Jonathan McPhillips.
On Saturday, 25 February at around 00:40hrs, police were called by the London Ambulance Service (LAS) to reports of a stabbing on Upper Street, N1.
Shortly after this, police were alerted to a second stabbing victim, also on Upper Street.
Father-of-two Jonathan McPhillips, 28, was found injured and taken to an east London hospital where he later died on Wednesday, 1 March. His next of kin have been informed.
Formal identification will take place in due course.
A post-mortem examination is scheduled to take place on Friday, 3 March.
The second victim, a 17-year-old boy was also taken to an east London hospital and has since been discharged.
There have been no arrests and enquires continue.
The Homicide and Major Crime Command (HMCC) led by Detective Chief Inspector Dave Whellams are investigating.
Detective Chief Inspector Dave Whellams said: "Jonathan's family have been left completely devastated by the circumstances which led to his death. His two young daughters will now grow up with a devastating loss that has deprived them of the chance to know their father.
"Almost a week has passed since the incident and we continue to piece together the events which took place in the early hours of last Saturday morning.
"At this early stage this appears to be motiveless attack and we have established that Jonathan, who was in the company of seven or eight friends out enjoying the evening. The group was approached by six or seven males, an altercation occurred and Jonathan was fatally stabbed.
"The Upper Street area is usually very busy on a Friday night into the weekend, and we know that there were a number of people out and about who would have seen the altercation or the stabbing. I am urging anyone who witnessed the incident or has any information to come forward. It's important that we progress this investigation and trace the people involved and this can only be done with your help.
"I am also appealing to the friends and family of those who are believed to have carried out this attack. If you have the slightest indication that someone who you know may have been involved I would urge you to make the police aware of your concerns."
