Two people were taken to hospital and five taken into custody following a brawl.
Officers and paramedics were called to Muswell Hill Road just before 10pm after receiving reports of an assault.
On arrival a 47-year-old man and 16-year-old boy were taken to hospital with stab injuries.
Four people were arrested on suspicion of grievous bodily harm (GBH) that night – incuding two 16-year-old boys, a 47-year-old man and a 28-year-old man – with a fifth – a 38-year-old man – arrested on suspicion of GBH today.
One of the 16-year-olds was further arrested for conspiracy to supply drugs.
Four of the suspects have since been released under investigation pending further enquiries, but one 16-year-old is still in custody though he remains in hospital.
Tamas Sarosi, working at Planet Organic in Muswell Hill Road at the time, witnessed the aftermath of the attack saying: “I saw blood on the ground. I was thinking, it’s another stabbing in London. I wasn’t happy that something like this happened outside my workplace.”
All five are being held in east London police stations.
Enquiries are continuing.
