Ten people have been arrested on attempted murder charges after plotting to “ambush” and kill Immigration Customs Enforcement (ICE) officers, officials said.

People dressed in black military-style clothing and body armour allegedly lured officials at the Texas immigration detention centre outside, before opening fire and injuring a police officer.

The group tried to draw officials outside at the Prairieland Detention Centre in Alvarado on Friday, shooting fireworks, damaging cars and vandalising the facility with graffiti, writing words such as “traitor” and “ICE pig”, officials said.

The commotion “seemed to be designed to draw US Immigration and Customs Enforcement personnel outside the facility, and it worked,” Nancy Larson, acting US attorney for the northern district of Texas, said at a news conference.

“It was a planned ambush with the intent to kill ICE corrections officers,” she added.

Officer shot in neck

Two unarmed corrections officers came outside to speak with the group. At some point, the Alvarado police officer arrived and was shot in the neck by someone who was in the woods, Ms Larson said.

The officer was treated at a hospital and released, the Johnson County Sheriff’s office said.

“Another assailant, who was across the street, nowhere near the corrections officers, shot 20 to 30 rounds at these unarmed corrections officers,” she said.

“There was an AR-style rifle found at the scene” that was jammed, she said. A flag saying “Resist fascism, fight oligarchy,” and flyers with words such as “Fight ICE” also were recovered near the facility, she said.
