Leslie Shields, 56 and his stepson Kevin Wardle, 29, have been jailed for a total of five years after being convicted of drug offences.
The sentence comes as part of ongoing Operation Sentinel activity to tackle serious and organised crime across the region.
The pair, both of Dene Crescent in Wallsend, appeared at Newcastle Crown Court on Tuesday (August 5), after officers discovered they were involved in drugs back in December last year and carried out covert tactics to bring the offenders before the courts.
Now Shields, who pleaded guilty to conspiracy to supply heroin and cocaine, has been jailed for three-and-a-half years and was ordered to pay a victim surcharge of £170.
His stepson Wardle, who pleaded guilty to conspiracy to supply heroin, was sentenced to 18 months behind bars.
Following the sentence, Chief Inspector John Bensley, of Northumbria Police, said police would continue to target those supplying drugs across Northumbria.
He said: “This has been a fantastic result for Operation Sentinel and the officers who put in a lot of time and effort to secure a conviction.
“Drug dealers prey upon some of the most vulnerable people in society and have no thought for anyone but themselves.
“The sentence sends a strong message to other potential offenders that we, along with our partner forces, are continuing our efforts to proactively target suspects and keep our communities safe.”
