May 18 (UPI) -- Authorities said Sunday night that officers arrested three teenagers, ending a weekend shooting spree through southern Austin that left four people wounded, including one critically.

The shootings began Saturday afternoon, with the first calls to police recorded at about 3:45 p.m. CDT. A shelter-in-place order was issued amid the shootings and was lifted shortly before 4:30 p.m. Sunday.

At least 12 separate shootings, mostly in south Austin, were recorded in the crime spree, according to authorities, who said at least two separate fire stations were struck, as were several buildings and homes.

Authorities had been searching Sunday for a stolen white Kia in connection with the shootings. When police pulled it over, three people exited the vehicle and ran. Officers pursued and arrested two suspects -- identified as a 15-year-old and a 17-year-old -- at the scene, authorities said.
