A video of a wealthy businessman beating a doorman at his luxury apartment building has sparked outrage in Mexico, where people have taken to social-networking sites to vent their anger.

The attack occurred in July of last year but did not come to the public’s attention until Tuesday, when the video of the incident went viral on YouTube.

The footage shows Mexican textile group owner Miguel Moises Sacal approaching Hugo Enrique Vera, insulting him several times and then delivering a brutal beating that left the man with two broken teeth and other lesser injuries.
