Huge weapons cache found in Sydney home

A huge cache of weapons and ammunition including ten guns, dozens of knives and swords and three crossbows has been found at a home in northwest Sydney.

A 64-year-old man has been arrested and is in hospital having been taken there for assessment, police say.

Detectives searched the Richmond home last Tuesday morning after a tip-off from the Australian Border Force about imported firearm parts.

They seized five rifles, including a semi-automatic, more than 2000 rounds of ammunition, some gun parts and accessories, three crossbows with arrows, and more than 100 knives and swords.

The detectives also seized ballistic vests, armoured helmets, handcuffs, documents, literature and a computer.

They later found another five guns, including pistols and handguns, after investigating a report of a suspicious bag hidden in a stairwell at the property.

Police said the resident of the home is expected to be charged with firearms and weapons offences upon his release from hospital.
