An early-morning pursuit near the US-Mexico border in southern Arizona escalated into a dramatic exchange of gunfire after a suspected human smuggler allegedly opened fire on Border Patrol agents and a federal helicopter, leaving the suspect critically injured and prompting multiple investigations.
The Arizona shooting unfolded shortly after 7 a.m. on Tuesday near Arivaca, a small rural community about 10 miles (16 kilometres) north of the border. According to Pima County Sheriff Chris Nanos, federal agents attempted to stop a pickup truck in the area when the driver failed to pull over, fled the vehicle and ran on foot.
