ALVARADO, Texas (AP) — Ten people have been arrested on attempted murder charges in connection with a shooting outside of a Texas immigration detention center that wounded a police officer, where people in black military-style clothing fired at authorities in a “planned ambush,” a U.S. attorney said.

One police officer was wounded after at least two people shot at officers outside an immigration detention center in Texas, according to a criminal complaint in federal court.

The Department of Justice filed a criminal complaint on Monday against 10 people who allegedly "organized an ambush" at an ICE detention center in Texas on the Fourth of July.
