Police say they’ve smashed a Brisbane drug trafficking syndicate following the arrests of 87 people since August last year.

More than 80 people have been arrested during an 11-month probe into an alleged large-scale heroin drug ring in Brisbane.

Police say 87 people, including two arrested in the city this week, face a total of 203 charges in relation to a drug trafficking syndicate.

During the investigation, carried out by the state’s drug squad from August last year, five kilograms of heroin and significant quantities of amphetamines, cocaine and cannabis were allegedly seized.

Almost $1 million in cash as well as $2.2 million worth of property, including four cars and a Harley Davidson motorcycle, were also nabbed.

On Wednesday, detectives raided a Brighton property where they allegedly uncovered two clandestine drug laboratories.

“It is believed the syndicate were responsible for multiple supply transactions of heroin each day in the Brisbane Metropolitan area,” a statement from police said.

One of those charged, a 37-year-old man, faced a Brisbane court this week charged with supplying drugs and manufacturing explosives.
