A pair of brothers and their pal who ran a drugs phone line under the names 'Woody', 'Tyson' and 'Rocky' forced a 15-year-old boy to deal cocaine and heroin.
Ratib Ali, 20 and Asad Ali, 19, and their housemate Janaid Rehman, 18, threatened the teenager, making him selling the class A drugs.
They told him he owed them money and the only way to pay it off was to be a mule.
He was driven around in a car and forced to hand drugs to buyers.
Cops investigating drugs supply and modern slavery across Greater Manchester smashed the operation last year.
Investigations revealed the trio operated three separate drug phone lines from their house on Royds Street West in Rochdale.
One was known by the names 'Woody', 'Tyson' and 'Rocky'. The other two were known as 'Kez' and 'Doctor'.
In April 2018, officers watched Ratib Ali and Rehman leave the house in a white VW Golf.

GMP Detective Chief Inspector Rick Hunt said: “This gang targeted and exploited a young boy, forcing him into a world of drug dealing and crime under threat of violence.
“He is now receiving help from specialist officers as he continues adjusting to a normal life away from the clutches of these despicable individuals.
“This was a large drugs conspiracy responsible for distributing a significant amount of class a drugs.
“But they were brought down thanks to the dedication and professionalism of our officers, who were able to utilise a broad range of surveillance and information gathering techniques to piece together this conspiracy."
