Two men have been charged after New South Wales Police investigated an alleged clandestine drug-manufacturing operation in Sydney's inner west. Detectives reportedly discovered a suspected drug laboratory at a Petersham property and seized additional items during a search in Mascot.

According to a report published on 27 October 2026, officers from the State Crime Command's Drug and Firearms Squad executed a search warrant at a property on Parramatta Road in Petersham at approximately 4:30pm on Monday, 26 October.

During the search, detectives allegedly located an inactive clandestine laboratory and seized items believed to be associated with the manufacture of methamphetamine. Specialist officers from the Chemical Operations and Diversion Team attended the property to examine the premises and assess the materials recovered.

Clandestine drug laboratories can pose serious risks because the manufacture of illegal drugs may involve hazardous chemicals, toxic fumes and potentially dangerous reactions. Investigators must carefully assess suspected laboratories and their contents to protect police, nearby residents and other people who could be exposed to hazardous substances.

Following the Petersham search, detectives searched a second property on Galloway Street in Mascot at approximately 5:30pm. Police reportedly seized a small quantity of prohibited drugs and electronic devices during that operation.

A 46-year-old man was arrested and charged following the search activity. He faces six alleged offences, including possessing substances and equipment connected with drug manufacture, supplying a prohibited drug in a quantity exceeding the large commercial threshold, and participating in a criminal group.

A second 46-year-old man was arrested at Old Bush Road in Yarrawarrah at approximately 5:45pm. He was also charged with six alleged offences relating to the investigation.

Police refused bail to both men. They appeared before a court on Tuesday, 27 October.

The investigation forms part of police efforts to identify and disrupt suspected drug-production and supply networks operating across metropolitan Sydney. Such investigations can involve searches at multiple locations, forensic examination of seized equipment, analysis of electronic devices and inquiries into the alleged roles of individuals involved.

Authorities have not publicly established the full scale of the suspected operation or detailed how long the alleged activity had been taking place. The discovery of an inactive laboratory also does not, by itself, establish when the equipment was last used or the quantity of drugs that may have been produced.

Investigators will need to examine the seized materials and other evidence to establish the circumstances surrounding the alleged offences. Further inquiries may help police determine whether other people or properties were connected to the suspected operation.

The case highlights the potential community risks associated with illegal drug manufacturing, particularly where hazardous chemicals or equipment may be stored in residential or commercial areas.

The charges against both men remain allegations. They are entitled to the presumption of innocence unless proven guilty in court.
