wo murder investigations have been launched in the space of just two hours after a stabbing and shooting.
Officers found a victim, believed to be in his 30s, suffering from multiple stab injuries after a fight between two groups.
He was given CPR but died at the scene in East Ferry Road.
Two hours later at 10.30pm a man in his early 20s was found with fatal gunshot injuries on Green Lanes, north London.
Armed police and the London Air Ambulance attended the scene and the man was pronounced dead at just before 11pm.
Minutes later police were called to a north London hospital after a 24-year-old man self-presented with non life-threatening gunshot wounds.
A third victim, in his 20s, who was believed to be riding past the shooting as it took place, was identified at home in Edmonton. He was taken to hospital with non life-threatening injuries.
Officers are in the process of contacting the murder victim’s next of kin but formal identification has not taken place.
A post-mortem examination will take place in due course.
There have been no arrests and enquiries continue.
Police have appealed for witnesses to come forward about the incidents, which are not believed to be linked.
DCI Wayne Jolley, who leads the investigation, said: “ We are investigating the brutal murder of a young man. This wanton act has left a family traumatised and mourning the loss of a loved one, while two more people have needed urgent hospital treatment.

Your information will be treated in complete confidence and you can always call Crimestoppers if you do not want to give your name.
“Although four people have been arrested on suspicion of murder; I want the public to understand this is still very early in the investigation and I am sure further arrests will need to made. We need to take the gun and the gunman off the streets and I need the public’s help to do that.”
Chf Supt Simon Crick, in charge of the North Area Command Unit, said: “This is a dreadfully sad loss of life and I understand how shocked the community will be.
