Weapons including a firearm, gel blasters and knives were found during a police raid in Thurgoona this week, which resulted in the arrest of a 22-year-old man.
Murray River police have linked the weapons haul to an alleged home invasion in the Albury area.
Officers conducted the raid on Tuesday and seized more than 80 items, including more than $50,000 cash, mobile phones, computers, drugs, a firearm and prohibited weapons.
The drugs allegedly include cannabis, cocaine and speed.
