Police arrested the man on Sunday evening on Burwood Road in Burwood after he allegedly tried to evade officers. He was taken to Concord Hospital for treatment of injuries sustained during the arrest, then transferred to Newtown Police Station. Charges have not yet been laid.
The incident began after 10:20am on Friday when the man allegedly confronted three witnesses over a stolen van taken from a nearby inner west suburb days earlier. He allegedly set fire to the van near the intersection of Williams Parade and Constitution Road in Dulwich Hill, brandished the shotgun, and fled on foot.
Police responded with tactical officers, a police helicopter, and a ground search that put nearby businesses, cafes, and schools into a lockdown that was lifted around 3pm on Friday.
The arrest was carried out by detectives from Strike Force Ranilo at around 11:30pm on Sunday. Police had earlier released a CCTV image of the fleeing suspect as part of the search.
