A critical incident investigation is underway after a man was shot dead outside a western Sydney police station when he opened fire on officers, ending an hour-long shotgun rampage.
Police say a vehicle stopped outside Penrith Police Station just after 9.30pm on Wednesday and the man approached a police vehicle with a pump-action 12-gauge shotgun and opened fire.
"Police returned fire and the man suffered a fatal injury. He died at the scene," police said in a statement early on Thursday.
