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.

A U.S. Army veteran arrested during an immigration raid at a California marijuana farm says he was sprayed with tear gas and pepper spray before being dragged from his vehicle on his way to work.

The majority of people held in the June immigration raids in Southern California were not criminals. Nearly half of them were Mexicans and most were men.
