Police tasered and arrested a 56-year-old Glenbrook man following a three-and-a-half-hour siege in bushland at Lapstone overnight.
Police responded to a 000 call about 9pm yesterday (Wednesday, March 6) from a man who said he was at Bluff Lookout at Lapstone with a loaded firearm.
Officers from the Blue Mountains and Penrith Local Area Commands, the Tactical Operations Unit (TOU), the dog squad and Operation Countdown established a command post in nearby Emu Road, Glenbrook.
While negotiators attempted to contact the man, TOU officers made their way into the bush.
Soon after this, police said a man emerged from the bush near four police officers who were maintaining a perimeter. It will be alleged the man produced a black handgun when he saw police, before running back into the bush.
He was followed by two TOU operatives and a police dog.
It will also be alleged the man confronted and challenged the officers before being tracked and stopped by the police dog.
Police will allege the man failed to comply with orders to surrender before they used a taser to arrest him.
They will allege a loaded firearm was found nearby and ammunition was also found in the man's pockets.
The man was taken to Springwood Police Station.
