90s film where a young black man is chased by a gang through a US city

From the 90s or may have been early 2000s. Set in a US city (I don’t know which one), the entire film takes place during the course of one night. The main character is a young black man who has somehow angered some members of a street gang, who pursue him relentlessly. The man turns to local residents for help, asking them to hide him, but many are too scared to get involved. Word gets out about his plight, and a local pirate radio station urges the community to help him however they can.
That’s all I can remember. Please help!
