The video from a 2006 killer whale attack at SeaWorld in San Diego has been released, and it shows the trainer being dragged under water during a performance.
U-T San Diego reports the 15-minute video was obtained through a Freedom of Information Act request by author David Kirby, who recently released his book "Death at Sea World."
The video shows trainer Ken Peters being pulled underwater when a whale, Kasatka, grabbed his foot and wouldn't let go.
Peters suffered puncture wounds and other injuries, but ultimately broke free. He still works at the park.
The video was first presented last fall by federal regulators in defense of safety violations they issued against the park following a 2010 death of trainer Dawn Brancheau in Orlando's SeaWorld.
