Cannabis worth $6m seized in NSW bust

Five people have been charged with more than 50 offences after NSW police dismantled a hydroponic syndicate and seized cannabis worth $6 million.

Four men and one woman were arrested after 19 search warrants were executed at Bankstown, Yagoona, Condell Park, Greenacre, Riverwood, Penshurst, Bexley, Campsie and Strathfield, from about 7am on Wednesday, as part of a task force targeting hydroponic operations.

More than 50 charges were laid.

"Make no mistake - this is organised crime. Those involved simply want to make a profit no matter the cost," Detective Chief Inspector Stuart Bell, commander of Redfern Region Enforcement Squad, said.

"We want to disrupt every aspect of their operation by not only taking way their infrastructure, but getting these criminals off the street.

"Hydroponic houses have the potential to put surrounding houses and people in danger and they can be anywhere. This group used a diverse range of suburbs to try and hide their activities."

He urged the public to be alert to what was happening in their neighbourhood and report any suspicious behaviour to police.
