Baby elephant attacks zookeeper

Video of an elephant knocking down and injuring his trainer at a zoo in Ohio in the US has been released.

It shows the animal pinning the keeper in a corner after being startled by his arrival in his enclosure.

The elephant then backs away before charging at the keeper, who has been in hospital since the attack three weeks ago.

The video was released by the Toledo Zoo and shows the keeper stumbling out of the enclosure while the elephant stands back.

The zoo's director says she iss not sure why the elephant turned on the keeper, whom the elephant had known since birth.

She says it looks as if he was startled and started play-fighting like elephants do in the wild.

The injured man and his family initially fought the video's release but changed their minds to show that the animal was not mistreated.
