Charlottesville, VA, police are investigating the assault of an officer who was reportedly knocked to the ground, swarmed by a group of masked subjects, and beaten during a demonstration marking the one-year anniversary of the violence in that Virginia city that left one woman dead.

The officer wasn’t hurt, but an investigation is ongoing, according to Fox News.

During a parallel gathering in Washington D.C., masked individuals allegedly affiliated with the ultra-left group Antifa were seen on cell phone video launching eggs and water bottles and shooting fireworks at police officers and journalists covering the march.

"In a tense scene about a half-mile from the White House, police appeared to shove back the advancing Antifa group," Fox News said.

One officer used pepper spray, but officials said no tear gas was used, according to reports.
