Video: May Day Protester Hits Cop in Downtown L.A.

Police are asking for the public's help in identifying the person who hit an officer Tuesday at a May Day rally in downtown Los Angeles.

The man hit the female officer in the back of the head with an object first thought to a skateboard.

The officer was wearing a helmet and was not seriously injured, but was taken to the hospital.

Authorities are now saying the object may have been a drum.

Video of the incident--called "Cheap Shot at A Cop"--has already gone viral on the Internet Wednesday.

Watch it in our media gallery.

LAPD Commander Andy Smith has said that whoever hit the officer--who did not fall, but did have a dented helmet--will be arrested.

Business Insider was quick to call the individual an Occupy LA protester in its coverage of the incident.

It will be interesting to see how Occupy LA responds, if that is in fact the case.
