Another shooting?

A neighbor called about 10:20 tonight saying that he'd heard maybe 20 gunshots (somewhere in the vicinity of 6th and P). I looked outside and the streets were full of police cars. A little later I saw an ambulance heading west on O Street. Still lots of sirens half an hour later. Anyone have any definite information about what happened?

UPDATE: This information from Insp. Burke of MPD 3rd Dist.:

At approximately 10 p.m., three black males wearing dark “hoodies” and armed with handguns, approached the complainant and fired at him – striking him in the leg. The complainant was admitted to [the hospital] in Stable condition. The CCTV did capture the incident and footage has been downloaded for review by our detectives’ office. The complainant, who lives on McCullough Ct. did not provide a motive for the shooting. There were numerous shell cases located on the scene – which corroborates the many accounts of gunshots. We’ll provide more details as they become available; Thanks for your patience.

This is from Cpt. McCoy: On Monday night at 10:20 PM a 22 year old male was shot in the leg in front of 1301 7th St., N.W. An MPD off duty was just inside the building and immediately requested assistance. Another MPD officer was conducting a building check across the street at 1330 7th St. and immediately responded to assist. As reported, there were numerous other officers assigned to the area and joined in a canvass for 3 black male subjects that were scene leaving the area. The injury sustained to the victim was non-life threatening. Anyone with information is asked to call 202-727-9099. Refer to Report Number CCN 048-668.

I know we all appreciate the information, and of course the quick police response. What I find pretty amazing is that the shooters would have the brass to try this with police presence virtually on the scene. (Of course, we don't know if this was plainly evident or not at the time.)
