Ten arrested in NSW drug raids

Ten people have been arrested in NSW following a string of drug raids in Goulburn and Sydney.

Police swooped on seven properties in Goulburn in the Southern Tablelands on Tuesday morning and allegedly seized methylamphetamine, cannabis, cash and property.

More than 100 drug-related charges are expected to be laid against six men and four women who were arrested and taken to Goulburn Police Station.

Police also raided a property in Carlingford in Sydney's northwest on Tuesday, and allegedly found methylamphetamine along with about three litres of a liquid believed to be GBL.

The operations were the result of a four-month investigation into illicit drug supply in the region.

"While a significant amount of illicit drugs have been taken off the streets, today's arrests are by no means the end of Strike Force Coull investigations, which will continue," said Detective Inspector Chad Gillies.
