A U.S. citizen and Army veteran who works as a security guard at a California cannabis farm said on Wednesday that U.S. officials arrested him during an immigration raid last week and held him for three days without explanation.

George Retes, a native of Ventura City, California, says he was pinned to the ground by ICE officials on his back and his neck after getting caught between protesters and authorities last week.

George Retes, 25, who works as a security guard for the Glass House Farms in Camarillo, was arrested last Thursday and released three days later without being charged with a crime
