Detectives investigating the fatal stabbing of 14-year-old Fares Maatou have made six further arrests bringing the total number of suspects to 10.
The group of males - aged 15, 18, 18, 22, 30 and 53 – were all arrested at an address in Leyton, east London on Tuesday.
The 15-year-old was arrested on suspicion of murder and possession with intent to supply class A and class B drugs.
The rest of the men were arrested on suspicion of assisting an offender and possession with intent to supply class A and class B drugs.
All were taken to various east London police stations and remain in custody.
Police had been called to the area at 3.56pm on April 23 following reports of a stabbing.
But Fares was pronounced dead an hour later and a post-mortem examination held at East Ham Mortuary gave Fares’s cause of death as stab injuries.
Fares, who was wearing his school uniform, was in possession of an e-scooter when he was attacked. Police said inquiries are continuing and they are keeping an open mind as to any motive.
It comes after three other 15-year-old boys were arrested last week on suspicion of murder.
They have been bailed to a date in late May.
So far in 2021, Scotland Yard has opened 13 homicide investigations where the victim was a teenager, 12 of whom were stabbed to death.
