Four people have been arrested in Dungannon following the seizure of drugs with an estimated street value of £330,000.
Two men, aged 73 and 20, and two women, aged 62 and 42, were held after suspected class A, B and C drugs were found in Dungannon during searches on Thursday.
Police said detectives from the Organised Crime Branch, assisted by officers from the Mid Ulster District Support Team and neighbourhood officers, made the arrests following searches at a business and two residential properties.
Drug paraphernalia was also seized along with other items including phones, a vehicle and a quantity of cash.
The 73-year-old man has since been released on bail while the other three suspects remain in custody.
Detective Inspector Kelly said: “From the various types and quantities of drugs seized it is clear that this was a highly active and large scale criminal enterprise and the seizures and arrests will cause a significant disruption to the supply of drugs in the Dungannon area.
“I would encourage anyone who has information about the use or supply of illegal drugs to contact police on the non-emergency number 101.”
