This device can safely and swiftly stop a speeding car in its tracks

Updated: 

A start-up company has created a device capable of locking a wheel of a speeding car and forcing it to stop.

The Grappler Police Bumper was designed to help police safely capture suspects avoiding arrest, and features various deployment methods to suit different situations.

The "tethered snag" activates the device with a flip of a switch, accomplishing a prompt and controlled stop. The "non-tethered snag" is best suited for fast lanes - while it won't stop necessarily stop a suspect in their tracks, it will flatten their tyre leaving a long skid mark for easy tracking.

The device is easily concealable and the tether can be released at any point - before, during or after a stop is made.

After several years of research, design and development, the Grappler is now at the early stages of manufacture - although several devices have already been produced and offered to law enforcement agencies to try.
