Hundreds of people defied an 11 p.m. curfew, as multiple fires were set and buildings and businesses were vandalized on the third night of protests in D.C. following the death of George Floyd.

Streets did not clear until an hour and a half after D.C. Mayor Muriel Bowser’s curfew kicked in. By then, multiple vehicles were set ablaze, the lobby of the AFL-CIO headquarters was burned, as was the basement of the historic St. John’s Church. D.C. Fire and EMS said it extinguished all the fires by midnight.

Activist Charlotte Clymer said she was among a small group of protesters who attempted to extinguish the fire at St. John’s Church. Clymer told DCist the fire was located in the nursery in the church’s basement, and that she and two others attempted to get inside to find a fire extinguisher when police arrived.

“There was this moment where we thought they were going to hit us with batons, and we had to just urge them and tell them there was a fire in the nursery,” said Clymer. “They had no idea.”

The D.C. fire department tweeted the fire was extinguished shortly after 11 p.m.

“Black activists were repeatedly urging calm on the front lines and these white protesters kept coming up to the front of the line throwing bottles and getting in cops’ faces and then running off, leaving black protesters to deal with the fallout,” Clymer said. “It was just demoralizing to watch.”

Mayor Muriel Bowser followed other major U.S cities and imposed a citywide curfew Sunday night, which remained in effect until 6 a.m. on Monday. Demonstrations stretched into early Monday morning, with some protesters wreaking havoc on both public and private property. Virginia Governor Ralph Northam also set a curfew in Richmond.

In Washington, the National Guard was activated for a second night in a row.

As the city’s curfew came and went, hundreds of people remained downtown. Law enforcement used flash bangs and tear gas to dispel protesters, according to social media reports.

Across town, the Metropolitan Police Department responded to two break-ins in the Friendship Heights and Tenleytown neighborhoods. Video from ABC 7 showed dozens of people breaking into a CVS in Friendship Heights.

“Several individuals have been detained in both incidents at this time,” MPD tweeted.

A handful of other nearby businesses —including Lord & Taylor, Rodman’s Discount Food and Drugs, and the Mazza Gallerie shopping center—were also damaged.

Other businesses around the city were looted or damaged, including a CVS and a Capital Bank near Farragut Square. Windows were broken at Alta Strada, an Italian restaurant, and at Busboys and Poets near Mount Vernon Square.

Earlier in the night, hundreds of protesters packed tightly together in Lafayette Square chanting George Floyd’s name.

Others continued to march and chant “Black lives matter” and “No justice, no peace,” along H Street, eventually encountering a line of police that prevented them from advancing. Protestors raised their arms as they stood face to face with police. Some threw objects at officers, who deployed flash bangs.

People who were marching joined demonstrators at Lafayette Square around 9 p.m., growing the crowd.

Firecrackers were tossed toward the line of police inside Lafayette Square. Some protesters hurled water bottles at officers, who blocked the water bottles with shields. Officers occasionally fired non-lethal rounds, sending some demonstrators running.

Makia Thorndyke, 20, said she was prepared to stay at the protest late into the night, despite concerns that police would use tear gas or rubber bullets. She said she is filled with a gut-wrenching feeling any time she encounters police, tensing up and reminding herself not to make sudden movements.

“That’s a traumatizing thing to have to deal with all the time,” Thorndyke said.

Lafayette Square was also the center of protests that began Saturday afternoon, which eventually swept across downtown and grew more chaotic throughout the night. D.C. police said Sunday they arrested 17 people overnight: 14 were charged with rioting, two with burglary and one with assault. The Secret Service said Sunday they arrested seven people total since protests began Friday.

Sunday marked the third night of protests in D.C., and around the country, after the death of Floyd in Minneapolis last week. For the District, it was also the third day of a gradual reopening, following a citywide stay-at-home order prompted by the coronavirus pandemic.

Hundreds of protesters started the day near Howard University’s campus around 2 p.m. and made their way toward the White House. The group marched down Georgia Avenue, stopping to kneel in silence as protesters held fists in the air. After reaching the White House, some kneeled again.

Around 4:30 p.m., protesters dismantled metal barricades and pushed into Lafayette Square.

Near Lafayette Square, Llacey Simmons and her 7-year-old son Cavanaugh Bell handed out free water and snacks to protesters. Cavanaugh wore a shirt that read, “This kid has had enough. End gun violence.” He stood on a sidewalk, offering to pump hand sanitizer into protestors’ hands.

As they stood on the sidewalk, some demonstrators briefly fled Lafayette Square for reasons that were not immediately clear. Simmons pulled her son closer but neither seemed shaken.

“If seeing people running and standing for change will prevent him from getting pulled over by a cop and getting shot, then that’s a risk I’m going to have to take,” Simmons said.

The crowd of protesters, which was racially diverse and seemed mostly populated by younger adults, thinned out as darkness fell. But hundreds of people remained behind barricades inside Lafayette Square as curfew approached, shouting at Secret Service and U.S. Park Police officers 20 feet away.

During a press conference Sunday afternoon, Bowser and Police Chief Peter Newsham commended the peaceful protests from Saturday and attributed the violent clashes that occurred later at night to a “small number” of people who set fires, looted businesses and attacked officers.

“D.C. welcomes peaceful protest, but we can’t have people come in and destroy property and hurt people,” Newsham said.
