A 19-year-old man has appeared in court charged with murdering a teenager.
Aminur Khan, of Robin Hood Gardens, Poplar, east London, is accused of stabbing 16-year-old Ajmol Alom to death on Monday night.
His appearance at Thames Magistrates' Court in Bow, east London, comes as detectives investigating the murder arrested a third man, aged 21, in connection with his death.
Another 19-year-old has already been arrested on suspicion of murder and remains in custody at an east London police station.
Ajmol, who has been described as a star pupil, was wounded in the thigh during the incident in Spey Street, Poplar.
Khan is also charged with the attempted murder of Ajmol's friend Azime Rob, also 16, who was stabbed through the cheek.
Both were taken to hospital, where Ajmol died. A post-mortem examination showed the stab wound to Ajmol's leg had been fatal.
Khan, who wore a grey T-shirt in the dock, spoke only to confirm his name, age and address during the two-minute hearing.
District Judge Gareth Branston remanded Khan in custody and told him he will next appear at the Old Bailey on Monday.
