A driver opened fire on a crowd of people surrounding the tour bus of rapper French Montana after a concert in Philadelphia, killing one person and injuring another, according to police.

The shooting happened around 11:30 p.m. Thursday as the entourage had arrived at a hotel near Penn's Landing after the rapper had headlined a sold-out show at the Theatre of Living Arts. Philadelphia police Chief Inspector Scott Small said a crowd formed around the bus, a car pulled up and someone began shooting.

"A large crowd of fans, as well as some of the entourage, were loitering and just hanging out," Small told reporters. He said one man may have fired back.

A 27-year-old man was hit in the abdomen and later pronounced dead at a hospital; another man was hit in the shoulder. Their names haven't been released.

Investigators were still questioning several people about the shooting Friday, but no arrests were announced, said Officer Tanya Little, a police spokeswoman. Investigators said they don't think the rapper or his entourage were targeted and neither victim appeared to be with the rapper's group.

The Moroccan-born rapper, who is scheduled to play Brighton Music Hall in Boston on Friday night, posted a photo on Twitter showing a police officer interviewing a person after the shooting. He also posted photos of himself with Philadelphia rapper Meek Mill at the show. The New York artist is touring to promote his upcoming debut album, "Excuse My French," which features Nicki Minaj.

Last month, three people were killed and five injured in a shootout and crash on the Las Vegas strip; police think that shootout may have started as an argument at the valet area of the upscale Aria resort-casino the same night French Montana was playing at Aria's signature nightclub, Haze.
