The Trump administration is taking a “zero tolerance” approach to attacks on law enforcement after a Texas police officer was shot outside a U.S. Immigration and Customs Enforcement (ICE) detention center.

The message came after similar incidents in other cities amid backlash against President Donald Trump’s immigration enforcement agency. 

An Alvarado, Texas, police officer was shot Friday night near the Prairieland Detention Facility, authorities said.

In Alvarado, a suburb of Fort Worth, several suspects were arrested after an officer with the Alvarado Police Department was shot at around 11 p.m. while responding to reports of a suspicious person, FOX Dallas reported. 

When the officer tried making contact with the person, shots were fired and the officer was struck in the neck. 

The officer was flown to a Fort Worth hospital for treatment and was later released.

Several armed suspects fled but were arrested with the help of the Johnson County Sheriff’s Office and other authorities, the news station reported.
