Two more people were arrested yesterday on suspicion of murdering Dagenham teenager Joel Adesina in Bethnal Green.
A 20-year-old man was arrested in London last night, and a woman, 18, was also taken into police custody in London yesterday.
The arrests come a day after a 20-year-old man was apprehended in Beccles, Suffolk, on suspicion of murder.
All three remain in custody.
Joel, 15, died three hours after being stabbed in a street fight late on December 5.
Previously, two men were arrested and taken into custody on December 8.
A 24-year-old woman arrested on the same day has been released on bail.
