New video appears to show Alex Pretti clashing with agents 11 days before shooting

A newly emerged video appears to show Alex Pretti in a confrontation with federal agents 11 days before he was shot and killed in Minneapolis.

In the video, a man who appears to be Pretti and others on the scene are seen shouting at agents blocking an intersection in Minneapolis on Jan. 13. A man who looks like Pretti is then seen kicking a federal vehicle before agents get out, push him and tackle him to the ground. Agents then fire gas into the crowd.

The agents get up and the man appearing to be Pretti walks away, a gun visible on his waistband.

ABC News does not know what happened before this altercation.

The Department of Homeland Security told ABC News on Wednesday that Homeland Security Investigations is reviewing the video.
