Six people were wounded in four shootings in the District during an 11-hour period over the weekend, but police said the incidents appear to be unrelated.

In the first on Saturday afternoon, police said a Northeast man was shot multiple times in the leg by two men who pulled up beside him in a dark blue vehicle on Hanna Place, SE, near 51st Street, SE.

Two more people were shot just before 8:30 p.m. Saturday in the 600 block of Otis Place, NW. The victims told police that a man began firing into a crowd. One woman from Riverdale was shot in the foot; the other woman from Southeast was shot in the leg. Both were taken to the hospital with non-life-threatening injuries.

About three hours later, police said two District men heard rapid gunfire while walking through the alley behind the 1600 block of 17th Street, SE. One of the men from Northeast was shot in the back and taken to the hospital. He is in stable condition, police said.

In the fourth shooting at 1:30 a.m. Sunday, two men from Silver Spring were shot in the 1400 block of Bangor Street, SE. One man was shot in the arm and the other in the abdomen.

Police did not provide information about suspects or motives for the shootings, and are continuing to investigate.

“These shootings appear to be isolated,” said officer Araz Alali, a D.C. police spokesman. “When there are shootings like this, there’s a perception that crime is on the rise. But overall, violent crimes are still down throughout the city.”
