Washington, D.C. police have released security footage of a drive-by shooting that injured at least eleven people early Monday morning in an attempt to identify the assailants.

“We have confirmed that we have 11 individuals that are injured. We have mostly gunshot wounds to the legs, extremities, hands, some graze wounds,” Metropolitan Police Chief Cathy Lanier confirmed during a morning news conference.

The video shows two cars pulling up along the sidewalk some time after 2:00 a.m., and then people collapsing in a row and scrambling as the driver opens fire.

Police say they don’t immediately know of a motive, and detectives are still interviewing witnesses and collecting bullet fragments and other evidence.

21-year-old Jonique Douglas is one such witness, it seems.  She had reportedly just come out of the Fur Nightclub around the corner when the shots began.

She recalled: “Everybody was screaming…They shooting like directly at us…It coulda been a bloody mess.”

It wasn’t immediately clear why the crowd was standing outside at that time of day, though it’s possible most of them came from nearby clubs.

“There is usually a pretty good crowd out here – Saturday night, Sunday night,” Lanier noted.

Here’s video of the shocking scene, with an emphasis on the assailants’ vehicles:

Commander Andy Solberg said that in the early hours of the morning, particularly on weekends, “a whole lot of people with cash in their pockets come out onto the street, and the guys from Tyler House are waiting for them. That’s when you get the holdups and that’s the source of the shootings in the neighborhood.”

But that’s just one theory, and it’s unclear whether any of the victims knew the assailants.

Except for one person who was shot in the back, Lanier said the injuries are not expected to be life-threatening.  The group was comprised of adults and one 17-year-old.

Police are offering a reward of up to $10,000 for information leading to the arrest and conviction of the suspects, asking people with information to call 202-727-9099.
