Police seized drugs and weapons including a replica AK47 and throwing knives after a car search in Butler on Thursday morning.

Police spokesperson Susan Usher said officers stopped two men in a car just after midnight and found a large sum of cash, cannabis, and three throwing knives.

A subsequent search warrant on a house in Persian St, Eglinton allegedly uncovered a replica AK47, a gas-powered hand gun, and a money counting machine, as well as cocaine, cannabis, and steroids.

The two 20-year-old Eglinton men were charged with weapon possession and drug possession with intent to sell or supply.

They are due to appear before the Joondalup Magistrates Court on December 14.
