The confiscated drugs are piled up before incineration

The haul included bags full of heroin, ecstasy and other drugs which have been confiscated by police over the last year.

The "rat on a rat" campaign - which encourages people to tell police about dealers via a confidential hotline - has led to 70 arrests in the Swansea area.

The scheme is expected to be adopted by all four Welsh forces this year.

Police say the close-knit nature of the community in Swansea has contributed to the success of the initiative.

South Wales Police Superintendent Tim Jones, said: "It was clear from the incredible reaction of the public that they supported us taking action against drug dealers.

The availability of heroin is an increasing problem

"So they gave us the information and we made arrests, took drugs off the streets, seized property and confiscated cash."

"Drug dealers are breaking down the fabric of our communities.

"They deliberately target the young and vulnerable in order to build and maintain their trade."

Rat on a rat was set up in an attempt to combat the growing availability of class A drugs such as heroin, crack cocaine and ecstasy.

South Wales Police drugs liaison officer Alan Murphy said: "We had to find a way to get information in a more indirect ways and Crimestoppers Wales provided us with the solution.

"Research told us that Crimestoppers Wales was an effective means for people to pass on information anonymously, as 80% of their callers said they would not contact the police directly."

Anyone with information about drug dealers in Swansea can ring 0800 555111 and pass the information on anonymously.
