WATCH: Video shows crash of police helicopter in Arkansas

Authorities have released video showing the crash of a police helicopter in Arkansas that left one person injured.

The video posted on Tuesday on the Little Rock Police Facebook page shows the Bell TH-67 on a platform at a police training facility with its rotors turning. The chopper and the platform start to move as the helicopter pitches and fails to gain altitude. A man comes out of a building, seeming to signal the pilot to land, as the chopper's skid catches the edge of the platform and the craft rolls. The helicopter's rotor touched the ground and broke apart.

Retired officer William Denio was injured in the August 16 crash.

Police had said a straight-line wind forced the chopper off the platform.
