(CNN) The leader of an armed militia that held hundreds of migrants at the US-Mexico border was attacked at a New Mexico detention facility, authorities said Wednesday. Larry Mitchell Hopkins, the 69-year-old leader of the United Constitutional Patriots, was treated for non-life-threatening injuries after the alleged battery this week at the Doña Ana County Detention Center in Las Cruces, according to a press release from the county. "He was attacked by other detainees," said Kelly Jameson, a spokeswoman with Doña Ana County. "We are still conducting an investigation, but it could be possible that three other detainees were involved." The FBI arrested Hopkins last week.
