Nellie’s Sports Bar, a gay bar in the city’s U Street commercial district, announced on Monday that it has dismissed a security company whose employee was captured on video dragging a Black woman down a flight of stairs inside the bar during the city’s Capital Pride celebration last Saturday.

The video of the male security employee dragging Nellie’s customer Keisha Young down the staircase and the brawl that erupted when other customers intervened has triggered expressions of concern by city officials and LGBTQ activists, including the local Black Lives Matter group that organized a protest outside Nellie’s on Sunday.

Young, who said she was injured during the incident, has said the security staffer mistakenly thought she was part of a group of customers who brought into the bar their own alcoholic beverages, which Nellie’s does not allow.

“Nellie’s Sports Bar has terminated, with immediate effect, the independent security vendor hired to protect our guests during Pride Week,” Nellie’s said in a statement released to the media.

“Our investigation into the matter is ongoing, and we will cooperate with any law enforcement investigation, however we do not need to wait for the investigation’s conclusion before we take decisive action,” the statement says. “We offer a heartfelt apology to all who witnessed the horrific events of this past weekend,” it says. “No matter what behavior occurred prior, nothing warrants mistreating and disrespecting one of our guests.”

The statement adds that Nellie’s will be closed this week “as we evaluate this regrettable situation.” It says all non-security staff will continue to be paid their regular wages during the temporary shutdown.

“In the interim, we will use this time to listen and understand what more we can do to create the safe and friendly atmosphere our guests have come to expect from Nellie’s Sports Bar over the past 14 years,” the statement says.

Brandon Burrell, an attorney representing Young, told D.C.’s Fox 5 News that Nellie’s had yet to offer an apology directly to Young. Fox 5 News reported on Monday that Young was considering filing a police report over the incident and a possible lawsuit against Nellie’s depending on how Nellie’s responds to Young’s concerns. 

A D.C. police spokesperson told the Washington Blade that Young had not contacted police to file a report about the incident as of early Monday.

The D.C. Alcoholic Beverage Regulation Administration, which issues liquor licenses to bars and restaurants, has opened an investigation into the Nellie’s incident, the agency confirmed to Fox 5 News.

The Capital Pride Alliance, the local group that organizes D.C.’s LGBTQ Pride events, including Saturday’s Pride Walk and Pridemobile Parade, issued a statement on Monday expressing concern over the Nellie’s incident.

“The Capital Pride Alliance condemns the reprehensible actions taken by Nellie’s staff over the weekend,” the statement says. “The incident resulted in Keisha Young being dragged by the hair down the stairs, which was a violent response to the trivial action of allegedly bringing into the bar a bottle of liquor,” the statement says.

“Capital Pride Alliance is committed to creating safe spaces for all,” says the statement. “We expect Nellie’s to take immediate, remedial action in response to this incident. Their response will impact the future of CPA’s relationship with Nellie’s.”

Nellie’s owner Doug Schantz couldn’t immediately be reached for comment.

D.C. Mayor Muriel Bowser also expressed concern about the Nellie’s incident when asked about it by reporters at an event on Monday.

“Obviously, entrepreneurs enforce rules in their restaurants, but they’re not allowed to assault anybody,” the mayor said. “If that’s a matter for the Metropolitan Police Department, we’ll take it up.”
