SPECIALIST police have established a crime scene at a Lismore Heights home on High Street believed to be a drug laboratory used to manufacture and produce cocaine.

Richmond LAC Detective Inspector Cameron Lindsay said the production of cocaine, if confirmed by forensics, would be unusual for the Northern Rivers.

"There are processes being used that we haven't encountered a lot of and that's why we're using a forensic chemist to examine exactly what process is being undertaken here," he said.

Det Insp Lindsay said police had discovered highly explosive and dangerous chemicals at the residential Lismore Heights property.

"Obviously it's a big worry for us to see these dangerous chemicals being used in a residential area," he said.

"We will allege that there were explosive chemicals involved and posed a real danger to the public."

NSW Fire and Rescue HAZMAT officers were also on the scene providing support to the police Chemical Operations Unit to ensure hazardous materials and chemicals were dealt with safety.

Det Insp Lindsay said the warrant to search the property and subsequent establishment of a crime scene was part of an ongoing investigation into the manufacture and production of illegal drugs in the region.

"We have a dedicated team of officers that are working on this and there will be more arrests," he said.

"There will be more search warrants.

"We're not going to rest until we continue to take action against these people who are making this type of poison in this community."

Late yesterday, no arrests had been made in relation to the drug bust, however Det Insp Lindsay said he was confident arrests would be made.
