PORTLAND, Ore. (AP) — Federal immigration officers shot and wounded two people in Portland, Oregon, on Thursday, authorities said.

The FBI’s Portland office said it was investigating an “agent involved shooting” that happened around 2:15 p.m. “involving Customs and Border Patrol Agents in which 2 individuals were wounded.”

The Portland Police Bureau said its officers responded and found a man and woman with apparent gunshot wounds. They were transported to a hospital and their conditions are unknown, the bureau said in a statement.

The Department of Homeland Security’s agencies include Customs and Border Protection and the U.S. Border Patrol.
