Akon fans beware: The sweet-sounding singer appears to have a penchant for violence - or at least controversial behavior - at his own shows.

First he got his freak on with some jailbait tease in the Caribbean.

Then there was whole fan-tossing incident that landed him in court.

Now this! At a concert on August 30 in South American, Akon became aggressive with a concertgoer - a female, obvs - and it was caught on video.

After crowd surfing to a camera stand away from the main stage, Akon appears to shove one fan off the stand and hit another (!?) upon arrival.
