David Ogoe, 34, of Bury Close in London, was arrested at a property near Acle in April 2021 after an investigation into the ‘Buzz’ drugs line.
The line, which brought Class A drugs into Norfolk in 2021, was run by Ogoe before he passed it on to a 16-year-old to operate.
After the arrest, Ogoe was taken to Wymondham Police Station for questioning where he was charged with two counts of being concerned in the supply of Class A drugs.
Appearing at Norwich Crown Court on February 8, Ogoe was sentenced to six years and seven months in prison after being found guilty.
He was also ordered to pay a victim surcharge of £190.
Investigating officer DC Rebecca Pitt said: “This result highlights that action will be taken against those who to continue distribute drugs and impact our local communities.
“If you are affected by the issue, we encourage you to report drug dealing and drug-related anti-social behaviour to Norfolk Police to help prevent further offences in Norfolk.”
