WATCH: Police officers walk over a lady during St. Louis protests

During protests in St. Louis, Missouri, following the acquittal of a white former police officer who killed a black man, video footage showed what appears to be an elderly woman being pushed back by an advancing line of police officers wearing riot gear.

After falling down, people can be seen trying to help the lady, who was wearing red blouse and a skirt, but are pushed back by the police officers. Officers then step over the lady and stand side-by-side on a portion of the street.

The lady, who laid on her back in the street after police officers walked over her, was eventually helped up by several policemen and detained.

Around 600 protestors marched on the streets of St. Louis after Jason Stockley was acquitted of first-degree murder for the killing of Anthony Smith in 2011, according to Reuters.

The former police officer said that he attempted to arrest Smith on suspicion of participating in a possible drug deal when Smith fled the scene. Smith was eventually shot in his car five times. Defense attorneys claimed that Stockley believed Smith had a firearm; however, prosecutors alleged that Stockley planted the weapon.
