A 20-year-old U.S. citizen from the Los Angeles area has been released from federal detention after he was violently arrested in a Walmart parking lot last week. Adrian Andrew Martinez was taken when he approached a group of heavily armed and masked federal agents who were detaining a Latino janitor at the shopping center where Martinez worked at a local Walmart. The agents attacked Martinez, throwing him to the ground and arresting him as they asked him for proof he was born in the United States. Martinez has since been fired by Walmart. His body is still covered in cuts and bruises, and he’s wearing a knee brace after being injured by agents in the attack.
