Two suspected drug dealers have been arrested after an estimated £17,000 of heroin was seized from a car in Gateshead.
At about 9.45am today police visited an address on Newman Terrace that was believed to be linked to criminal activity.
As part of the operation officers carried out a search of black Land Rover discovery and found nearly a kilo of brown powder suspected to be heroin separated in bags.
The drugs will be sent off for forensic testing but it is estimated the Class A drugs have a street value of more than £17,000.
Two men - aged 46 and 41 - were arrested by Northumbria Police detectives and remain in custody as an investigation into drugs supply continues.
Detective Chief Inspector Paul Knox said the work was carried out as part of Operation Sentinel, the multi-Force crackdown on organised crime.
He said: "These are Class A drugs that were found after officers acted on information they had received from members of the public.
"Sometimes that kind of information can come to nothing but on this occasion we were able to make a significant seizure.
"These drugs would have been destined for the streets and have an estimated street value of tens of thousands of pounds.
"It is a fantastic result and comes on the day where officers also seized an estimated £200,000 of amphetamine.
"These seizures show our commitment to tackling organised crime and this type of disruption activity will continue under the banner of Operation Sentinel.
"But we need your support and we would ask you to contact police if you have any information about organised crime or want to report suspicious activity in your neighbourhood."
Operation Sentinel has seen Northumbria Police join forces with Durham, Cleveland and the North East Specialist Operations Unit (NERSOU) to tackle serious and organised crime.
Anyone who wants to report suspicious behaviour, or information about organised crime, can do so by calling police on 101 or Crimestoppers anonymously on 0800 555 111.
