Four young men in their 20s have been rushed to hospital after a quadruple stabbing in north London.
Police and the London Ambulance Service scrambled to Fraser Road, in Edmonton, at about 6pm to reports of a fight.
Once there, they found multiple men with stab wounds and all four have been taken to hospital.
A spokesman for the police said one of the men has been discharged from hospital, but the conditions for the other victims is not known yet.
Police said two cars at the scene, which had crashed into each other, were also found.
A crime scene was put up on Fraser Road while the street was closed off for emergency services to look at.
The violence comes just 24 hours after three men were injured after a suspected drive-by shooting on Gordon Road, just under one mile away.
The spokesman added the police is treating both incidents as linked.
A 16-year-old schoolboy was among those injured after police said a shotgun-wielding man drove up to a car and fired shots.
The shooting happened at about 6pm and, according to officers, the victims were sat in a parked mini cab before they were approached by another car that drove alongside them.
Police believe two men exited the car and one was armed with a shotgun.
Two shots were fired into the mini cab where the men were sitting, leaving two 22-year-old men and a 16-year-old boy injured.
None of the victims are in a life-threatening condition, although officers said one of the males has possibly life-changing injuries.
No one has been arrested for the attack, or the stabbings in Edmonton.
