A third man has faced court charged after fleeing a vehicle stop in Broken Hill.

The alleged proceeds of a home invasion in South Australia were seized during the vehicle stop.

A front seat passenger from the van ran off, while the driver, a 49-year-old man, was arrested by police.

Following a forensic search of the vehicle at Broken Hill Police Station, police allegedly located 14 firearms, a further semi-automatic loaded shotgun and a large quantity of collectable coins and other related cash located.
