The Grappler Police is a new system designed to stop fleeing vehicles in the U.S. It is installed under the front bumper of police cars and uses a mechanical arm resembling a hook to grab the rear wheel of a fleeing vehicle. In one incident, this device caused the rear axle of a Chevrolet Cruze to detach, leading to the closure of Interstate 96 during peak hours. The police attach the hook to the rear wheel as they approach the vehicle, but in this case, the driver attempted to continue driving despite the hook until the vehicle became inoperable.
