Six police officers were injured and 217 people were arrested in Washington, D.C. Friday after a small group of protesters grew violent throughout Donald Trump’s inauguration day, according to the D.C. Interim Police Chief Peter Newsham.

Just before Trump’s inaugural swearing-in speech at about 10:30 a.m. ET, some protesters began damaging four businesses and several vehicles, according to WTOP. Some of the damages included broken windows at a Starbucks and several small fires were started by igniting trash cans on K Street. Officers also had used pepper spray and shot out flash-bang grenades to keep the demonstrations at bay from the inauguration parade route along Pennsylvania Avenue, reported NBC News.

Around 4:30 p.m., protesters began setting a limo on fire with the phrase “We the People” spray painted alongside an anarchy symbol, tweeted by Matt Pearce, a Los Angeles Times reporter. A minority of protesters also began pulling bricks from the sidewalk and throwing them at police, causing police to respond with force and set off more percussion bombs.

Anti-Trump protests have simultaneously been going on in New York City throughout the day as well.
