A man has died in a suspected suicide after a siege west of the Blue Mountains that left heavily armed police fired on.
Police were called to Bowenfels, near Lithgow, just after midday on Sunday after concerns were raised about a dispute between a man and woman at a house.
The couple spoke to police briefly before going back inside, locking the door and refusing to come out, New South Wales Police said on Monday.
The most heavily armed NSW Police, Tactical Response Unit and negotiators were called in as officers set up a cordon around the house and attempted to de-escalate the situation.
Police feared the man had access to guns and shots were fired at police around 4.20pm.
The officers fired back, but no one was injured.
Negotiators tried to speak to the two overnight but they refused to come outside, police said.
Crime scene photos released online show the tactical unit’s BearCat armored vehicle parked on the street Monday morning.
