(CBS/ AP) A Philadelphia police officer used a Taser gun to apprehend a fan who ran onto the field during a Phillies game Monday night, and the team and the police are investigating whether it was an appropriate use of force.
The fan, wearing a baseball cap, red T-shirt and khaki shorts, hopped a fence and scurried around the outfield at Citizens Bank Park, eluding two security officers in the bottom of the eighth inning against the St. Louis Cardinals.
One officer used a Taser and the fan went down in a heap (video).
