At least six people were shot Monday night in the District, including one in Georgetown near the scene of the traditional Halloween revelry, according to accounts from police and witnesses.

The Georgetown shooting occurred just before 11 p.m. on M Street, one of the neighborhood’s main arteries, which is traditionally filled with people in and out of costume, drawn to a celebration that has become a Washington custom.

The victim, who appeared to be a teenager, was lying on the sidewalk in the 2800 block after the shooting, said a restaurant owner in the area.

According to the Associated Press, the victim was taken to the hospital in critical condition.

Sofiene Ben Mansour, owner of George’s falafel restaurant at 28th and M streets, said he heard three gunshots about 10:50 p.m.

The shots set off a scramble amid the throng in the street, he said, with people “just going all over.”

According to the accounts he heard from witnesses, Ben Mansour said, an automobile passed between two groups of people, and shots were apparently fired from it.

It threw a fright into the crowd, he said, leaving people talking rapidly and “just scared.” He said they were “saying ‘like, a car just shot somebody.’ ”

Earlier, two people who were described in one account as teenagers were shot and wounded in the Petworth area of Northwest Washington.

That shooting occurred about 9 p.m. at Georgia Avenue and Decatur Street NW.

About an hour later, another shooting occurred a few blocks away at Ninth and Crittenden streets NW. Police said they had no immediate indications that the two incidents were linked. It appeared that none of the three Petworth victims suffered a life-threatening wound.

About 8:40 p.m. in Northeast Washington, a teenager was shot near the New York Avenue station on Metro’s Red Line. He was grazed by a bullet, police said.

About 10:30 p.m., a man was reported shot in the 4400 block of Seventh Street SE, police said.
