Special Judge Deepak Garg awarded the punishment to Dinebari Debari along with a 29-year-old Punjab resident Sanjeev Kumar in the case under the Narcotic Drugs and Psychotropic Substances Act and also imposed a penalty of Rs one lakh on each.
"The prosecution has been able to prove its case beyond reasonable doubt," the court said.
According to the prosecution, in November 2010, Kumar was apprehanded on a tip off and over four kilograms heroin was recovered from his possession.
The police later filed a charge sheet against the accused persons before the court.
During the trial, however, the accused persons had pleaded not guilty and claimed that nothing was recovered from them and they have been falsely implicated in this case.
