A newly released video shows 37-year-old Alex Pretti confronting federal immigration officers on a Minneapolis street 11 days before he was fatally shot in another encounter with Customs and Border Protection agents, a Pretti family representative confirmed to CBS News Wednesday. It shows Pretti confronting federal agents along with other protesters. The vehicle then stops, and federal agents emerge and tackle him to the ground. The video does not indicate whether Pretti was detained by federal officers following the Jan. 13 incident. The agents involved in the incident have been placed on leave, a federal law enforcement official told CBS News Wednesday.
