More than 100 immigrants were pepper-sprayed at an Immigration and Customs Enforcement detention center in Louisiana this weekend, according to a source with knowledge of the matter.

The detainees were pepper-sprayed at the ICE Processing Center in Pine Prairie on Saturday, just a day after guards pepper-sprayed more than 30 immigrant detainees at a separate facility in rural Louisiana.

The incident in Pine Prairie was not publicly disclosed.

The inmates at Pine Prairie — where more than 1,000 ICE detainees can be held at a time — were pepper-sprayed after they demonstrated in the center’s yard, the source said. The inmates were then taken to a separate part of the facility to be decontaminated.

After this story was published, Bryan Cox, an ICE spokesman, confirmed the incident in an email to BuzzFeed News.

Cox said that a "group of ICE detainees refused to depart the outdoor recreation area at the Pine Prairie facility Friday evening."

"After repeated attempts by facility staff and ICE personnel to disperse the group and restore orderly operation of the facility, a brief, calculated use of pepper spray was employed Saturday morning."

He added that no one was injured in the incident.

But the advocacy group Freedom for Immigrants, said 115 immigrants who had been hunger striking for more than five days at the detention center "were tear gassed, shot at with rubber bullets, beaten, placed in solitary confinement, and blocked from contacting their families or attorneys."
