Eight people were wounded in Philadelphia in a spate of shootings over a four-hour period Thursday night.

In one incident, which happened at about 11:45 p.m. in the city's Kensington section, three people were were wounded after two masked assailants fired at least 15 gunshots.

About 15 minutes earlier, police were called to Cresentville after two men were shot a few blocks apart.

In the Kensington shooting, two men, ages 20 and 36, and a 21-year-old woman were shot on the 100 block of East Somerset Street.

All three were taken to Temple University Hospital, according to police radio reports.

Chief Inspector Scott Small told reporters at the scene that at least 15 shots were fired from  two separate handguns.

Two male suspects fled in an unknown direction after the attack, Small said.

Investigators stopped a vehicle that was seen driving away from the scene and said the female driver was acting suspiciously. Detectives were questioning the woman and holding the vehicle for further investigation, Small said.

The triple shooting came after two other men were hospitalized after shootings in Cresentville. At about 11:30 p.m., officers were called to a shooting on the 5900 block of Palmetto Street.

A 19-year-old man was shot in the back in an alley there, police radio reports said. In a possibly related shooting, another 19-year-old man was shot a few blocks away.

Further details about the late-night shooting victims weren't immediately available.

Earlier in the night, a man was critically wounded in a West Philadelphia shooting at about 8:45 p.m., and two people were shot in Strawberry Mansion at about 7:40 p.m.

No arrests were reported in any of the incidents. Motives for the shootings also weren't immediately known.
