The 16-year-old victim was lured to Gordon Road in August 2018 where a Ford Mondeo pulled up and he was attacked and forced into the car.
The group, which was led by Isaac Donkoh, took him to the home of one of the captors.
The victim was made to strip naked and hit with a metal pole over his face, back, legs and arms.
His hair was forcibly cut with scissors, during which time he was slapped in the face, forced to kneel and kicked hard in the head.
Donkoh tried to pour boiling water over the victim’s head, resulting in scalding the victim’s feet, causing serious injury.
He was also forced to swallow a cannabis joint in the sadistic assault, which was filmed by 22-year-old Donkoh, from Chelsea, on his phone.
The victim was then made to called his parents to pay a £1,500 ransom to secure his release.
Donkoh, a member of a Newham-based gang, was sentenced to 12-and-a-half years in jail.
Four boys, aged between 14-16, were also given sentences ranging from 30 to 42 months.
Prior to the court case, the victim had been contacted on Snapchat and offered £5,000 if he dropped the charges and didn’t attend court.
Lead investigator, Jim McKee, said: “This was an extremely violent incident, which has had a profoundly distressing impact on the victim and his family.
“While the physical scars of that night have started to heal, I believe the psychological impact on the victim has been lasting.
“Donkoh fronted drill music videos for his gang which goaded rivals and recruited boys as young as 14 to commit serious violence.
“I believe that removing Donkoh from the streets of Newham has done a great deal to reduce serious violence in the borough, as we identified a direct correlation between his drill videos, which glorified violence, and shootings and stabbings on the streets.”
