WASHINGTON (NYTIMES) - A 15-year-old boy was killed and three adults, including a police officer, were shot when gunfire erupted on Sunday night (June 19) at an unauthorised music event in a Washington DC neighbourhood known for its nightlife, the authorities said.
The Metropolitan Police Department had shut down the event, known as Moechella, a free street festival near the city's culturally storied corner of 14th and U Streets Northwest, after violence earlier in the evening, including a fight between attendees, police said.
As police and emergency medical workers cleared the area to treat people injured while fleeing a disturbance, "several individuals were shot", Chief Robert J Contee III of the Metropolitan Police Department said at a news conference late on Sunday.
Mr Contee said that the officer who was shot was expected to recover and that the two other adults were in stable condition. He did not say whether a suspect or suspects were in custody.
The circumstances of the shooting remained unclear late on Sunday, but he said that police officers did not fire their weapons.
Mr Contee said he wanted to ensure that people would be held accountable for holding events without a permit.
"This is one of the reasons we don't want events (without permits) taking place in our city," he said.
"Unfortunately, things like this can happen when you have the wrong mix of people, or people who introduce firearms into a situation."
The chief expressed frustration at the number of illegal firearms in the area, noting that police officers had discovered several such weapons earlier in the evening.
"Illegal firearms in the hands of people who should not have them make events like this unsafe for people who just want to enjoy the beautiful weather, who want to enjoy Father's Day, who want to enjoy our city," he said.
The shooting occurred at a festival The Washington City Paper described as "a free, go-go band-led event full of Black cultural spirit and anti-gentrification passion".
The newspaper said the event's name blends slang for friend - "moe" - with the name of the music festival Coachella.
An event organiser, Mr Justin Johnson, who is also a rapper and an activist known as Yaddiya, could not immediately be reached for comment.
"We're doing something for the people that's inclusive," he told the City Paper. "I don't really feel like it's a Juneteenth event if you're charging a lot for it."
The shooting unfolded in the aftermath of a series of high-profile gun killings, including two massacres in May: one at an elementary school in Uvalde, Texas, that left 19 children and two teachers dead; and a racist attack at a Buffalo, New York, supermarket in which a white gunman killed 10 black people.
This month, a brawl turned a packed Philadelphia street into a scene of terror after two men pulled out guns and began firing wildly at each other. By the time the gunfire ended, three people were dead and 12 more were injured.
