Police in the southwestern US state of Arizona said late Friday that they caught a suspect in a spate of shootings targeting motorists on a busy freeway.
"We got him!" read a tweet from Arizona Governor Doug Ducey.
A SWAT team from the Department of Public Safety "is in custody of the individual suspected of I-10 shootings. Apprehended moments ago."
At least 11 shootings have taken place on or near Interstate 10 in Arizona since August 29, including a semi-trailer being struck in the side by a bullet, police told AFP.
The only injury has been a teenage girl who was cut by flying glass when the window of the car she was traveling in was shattered by a bullet.
Colonel Frank Milstead, head of the Arizona DPS, said the shootings amount to "domestic terrorism" and a reward of $20,000 was being offered for information leading to an arrest.
The first shootings saw two cars and an empty tour bus being struck by bullets in separate incidents.
