NSW Police arrested two alleged contract criminals after seizing hand grenades, firearms, and drugs during raids on a south-west Sydney safe house.

The operation removes high-grade explosive weaponry from the streets, which police said prevents gangs from escalating violence within the region.

During the search of the residence, officers discovered six live hand grenades [1]. The seizure also included eight firearms [2] and a quantity of illicit drugs with an estimated value in the millions of dollars [3].

Authorities identified the location as an alleged safe house used by the suspects. The raid took place on Wednesday night as part of an effort to disrupt criminal networks operating in New South Wales.

Police said the recovery of the grenades is particularly significant given the potential for mass casualties if such weapons are deployed in urban environments. The two suspects remain in custody following the operation.

Investigators are continuing to process the evidence recovered from the scene to determine the origin of the weapons and the distribution network for the seized drugs. The scale of the narcotics seizure suggests the house served as a major hub for illicit trade in the south-west sector of the city.

Police seized six live hand grenades, eight firearms, and drugs potentially worth millions

The discovery of military-grade explosives alongside large quantities of narcotics indicates a high level of sophistication in local organized crime. By targeting 'safe houses,' NSW Police are attempting to dismantle the infrastructure that allows contract criminals to store weaponry and distribute drugs away from public scrutiny.
