Investigation launched into TSA handler's aggressive treatment of bomb dog at Detroit Metro Airport.

The Transportation Security Administration is investigating a video that shows a TSA agent aggressively handling a bomb-sniffing dog at Detroit Metro Airport. The video, which was shot by a Reddit user from Delta Sky Club at the airport, shows the dog and handler walking back and forth through the terminal with the handler aggressively jerking the leash and appear to drag the dog in some laps. The federal agency said it had shared the video with its local office in Detroit and that the worker wouldn’t be handling any dogs until the investigation was completed.
