A pedestrian was reported struck by a vehicle near the Verizon Center on Friday night at the time of a protest there against grand jury actions in New York and Missouri.

There was no immediate indication whether the pedestrian was linked to the protest, and the extent of any injury was also unclear.

However, the 11 p.m. incident added to commotion connected to the demonstrations, in which protesters have marched through downtown, shutting down several intersections temporarily as they went. In another matter that appeared to contribute to tumult in the area, an arrest was made by Metro Transit officers.

A spokesman for Metro said the officers took someone into custody in an incident that was not linked to either the protest or to the nearby Gallery Place Metro station.

D.C. Police said demonstrators were moving through Northwest D.C. near the Verizon Center after blocking roads in that area earlier.

Authorities said 7th and H streets NW is “open to traffic” in a message on Twitter. Police said just before 8 p.m. that the protesters were moving westbound in the 900 block of H Street NW and that a group of protesters were headed northbound at 14th and K streets NW.

They also reminded drivers that rolling street closures were in effect.

Protesters are no longer blocking an intersection near the Verizon Center and are moving east on F Street NW, according to D.C. Police.

Authorities said in a tweet that the demonstrators were headed east in the 700 block of F Street NW and that there would be “rolling road closures in effect.” Traffic around the Verizon Center remained congested as demonstrators walked the streets. The demonstrators have done several moments of silence and “die-ins” for around four hours to recognize the four hours that Michael Brown’s body was left in a street in Ferguson.

At one point, about 50 protesters lay silently in the street in a symbolic remembrance of Eric Garner, who was killed in a chokehold position after a confrontation with New York Police Department officers. Demonstrators shouted “If I can’t breathe. You can’t breathe.”

Some protesters marched in D.C.’s Chinatown area Friday evening and blocked 7th and H streets NW near the Verizon Center, as a Wizards basketball game was about to start.

The demonstrators stood in the street in the area of Gallery Place at 7th and H streets NW. Police said traffic in the area was slow as a result of the protest and said in a Twitter message that the protesters were blocking the 7th and H street intersection. Some protesters staged a “die in” in the crosswalk at 7th and H streets NW. And there were some reports of protesters chanting, “If I can’t breathe, you can’t breathe.”

It was not clear how long the protests would last. There is a Wizards game Friday evening at 7 p.m. at the Verizon Center.

The protest crowd appeared to be growing quickly from a few dozen to more people as they stood in the roadways around the Verizon Center.

Metro said in a tweet that several of its bus routes may be affected by the protests. Those routes include the 70, 74, 79, 80, P6, X2 and X9.

Protesters marched down 17th Street NW midday Friday as they headed toward the White House.

It did not appear that the protesters were creating any sort of traffic jams, and D.C. Police said they had not closed any roads as a result.

For the last few days, several protests have occurred throughout D.C. — and across the country — in response to grand jury decisions in cases of police shootings in Ferguson, Mo., and Staten Island, N.Y.
