Police in the District and Prince George’s County are investigating several violent incidents that occurred Tuesday night and early Wednesday, including a multiple stabbing in a club in the heart of the Adams Morgan night-life district.

Four people were wounded, although not seriously, in that attack, D.C. police said. It occurred about 3:45 a.m. in the 2400 block of 18th Street NW.

Officer Araz Alali, a police spokesman, said three men and one woman were slashed with a sharp object during a dispute inside the club. He said the victims were taken to area hospitals with minor injuries. They did not provide a description of their attacker to police.

Police Chief Cathy L. Lanier ordered the club, District, to temporarily close, Alali said. Lanier has the authority to issue an emergency decree shutting any establishment holding a liquor license in the city for 96 hours if she thinks there is a public danger. A hearing before the D.C. liquor board determines whether the bar can reopen or face further punishment.

In an interview last month, Lanier said she was concerned over violence at clubs and bars after seven people were killed in or outside night­spots last year.

In Prince George’s County, police said two men were shot and wounded about 11:45 p.m. Tuesday in the first block of Pepper Mill Drive, near Capitol Heights and Seat Pleasant.

Officer Nicole Hubbard, a county police spokeswoman, said the wounds did not appear to be serious. She said police knew of no motives or suspects in the attack.

About 1:15 a.m., Hubbard said, a man was shot in the 3100 block of Branch Avenue in Temple Hills. The address police provided is a hotel near the Naylor Road Metro station, although police could not say Wednesday morning whether the shooting occurred inside the hotel or on the street.

Hubbard said that a patrol officer responding saw a large group of people walking toward the Metro station and that some of those people are being questioned. Hubbard said investigators have not yet determined whether that group is connected to the shooting.

“We’re still working to identify a suspect and motive,” she said.
