While the Houston Dynamo caused few problems for FC Dallas on the pitch on Sunday night, Toyota Stadium security had their hands full with several incidents that culminated in the mass removal of the visiting supporters' section with around 15 minutes of the game left to play.This was the scene as security staff, as well as Frisco PD officers, requested that Dynamo fans retreat to their chartered buses which were parked a short distance from the east gate, close to the section.
