Circus elephant goes mad. how come?

hi. i am in southern asia. i just came back running as fast i could from a local circus. in the circus, an elephant was to perform some tricks to entertain the crowd. as soon as the handler hit the whip to the ground to signal the elephant to dance, the elephant instead grabbed his handler by the trunk and threw him with such force that the handler was tossed at least 60 to 70 feet away. unfortunately the handler couldn't make it. the elephant then started breaking anything that he sees and then charged at the audience. he grabbed some unlucky few from the audience and severely mauled them. by then everyone started running away and there was lots of screaming everywhere. i too ran away as fast as i could and made it back. the elephant was on a rampage. what happened? why did he act this way in the midst of a circus performance?

Circus elephant goes mad. how come?
it was either in 'must' when they get aggresive, or he was abused to train him, particularly with a whip
Reply:because elephants are usually abused at circuses so he or she was making a break for it
Reply:the elephant had peanut for lunch, and it was a salted.
