PEEL detectives have seized a significant amount of guns, explosives, drugs, cash and items suspected to have been stolen following a search warrant executed on a North Dandalup property this week.
Detectives raided the house on Wednesday and uncovered the massive haul which included three handguns, two rifles and ammunition.
Detective senior constable Dave Hackett said the firearms were unlicensed.
No one was home at the time of the search and charges have yet to be laid in relation to the seizure.
Investigations are continuing.
