This is an example of a Delay of Game violation by a coach on the bench. Bench personnel may not interfere with a ball that crosses over the plane of the boundary line if an opponent has an opportunity to save the ball. On this play, the player in the blue uniform has an opportunity to save the ball, but the opposing coach reaches out and interferes with the ball. This is a delay of game violation, and note that the first offense is a warning, and the second offense would be a technical foul.
