A sixteen year-old is one of two people arrested following the murder of teenager.
Yesterday (August 22) a man aged 20 and male 16 year-old were arrested on suspicion of murder.
Both were taken to east London police stations and have since been bailed to return to a date in late September.
Their arrests follow the stabbing of Kacem Mokrane, 18, on Thursday, 16 November 2017 in Mount Pleasant Road, Walthamstow.
Kacem died four days later from his injuries
A post mortem examination took place at Walthamstow Mortuary on Friday, 24 November and gave the cause of death as multiple organ failure following a stab wound.
Police were called to reports of a group of males armed with weapons at the scene at around 11.15pm on the day of the attack.
Five men who were arrested previously have all been released under investigation.
Detective Chief Inspector Dave Whellams, leading the investigation, said: "Kacem was attacked and murdered in the street.
"Our investigation continues to make progress but I would ask anyone who has information, no matter how insignificant it may seem, to contact my officers - it could prove vital to this investigation."
