Police said several people got out of a vehicle and opened fire on a crowd at Kensington and Allegheny avenues in the Kensington neighborhood at about 10:45 p.m. Saturday night.
Police said a 23-year-old man, a 27-year-old man and two 24-year-old men were seriously injured.  Two other 24-year-old men and two 40-year-old men were in stable condition, as was a 23-year-old woman.  Police said at least 40 shots were fired.  No arrests were immediately announced.
Deputy Police Commissioner John Stanford said police could not immediately determine a motive for the shooting.
“At this time, it appears that these individuals may have spotted someone they wanted to shoot at, got out of the vehicle and started shooting at the group of individuals that were there.  We don’t have much more than that in terms of motivation,” Stanford said.
There were police officers in the area who heard the shots, Stanford told WCAU-TV.
“Our men and women are where they’re supposed to be in the sense that they’re out here patrolling, but we’ve got some brazen individuals in this town who don’t care,” he said.  “They don’t care how many police officers are out here and some of them don’t care how many people are out here.”
