Six people were hurt after two police helicopters collided at the Pasadena Police Department's heliport in Altadena, Calif., on Saturday. The injuries were thought to be minor and the cause is under investigation. CBS News reported the blades of the OH-58 Kiowa helicopters touched. It's not clear whether one or both of the aircraft were in the air at the time. News photos showed extensive damage to both, with one of the helicopter's tailboom severed.

The helicopters were carrying a total of five people. One of the injured was on the ground. All were taken to hospital and all were reportedly released by Sunday. It was raining heavily at the time of the crash.
