LINEUP: Here's What You'll See on Night 3 of the RNC on Fox News!

Let's Go Behind the Scenes with Bret Baier at the RNC!

An American flag was set on fire and people were shoved to the ground, including a Cleveland police officer, during a protest outside the Republican National Convention.

Video captured by Fox Business showed protesters removing the flag from a package and setting it on fire. As police tried to reach the flag-burners, there was pushing and shoving, and the protester and officer fell to the ground.

It appeared that one of the protesters was arrested.

Fox Business's Connell McShane was on the scene when the incident happened. He reported that Cleveland's police chief informed him that open burning of any object is in violation of city law. He said that officers were hoping to minimize arrests, but would respond quickly if necessary.

Police reportedly also arrested a woman who was also filmed attempting to burn the flag.
