About 30 people including Princeton University professor Cornel West have been arrested outside a New York police station during a protest of the police department's policy for stopping, questioning and frisking people.

The group of activists, religious officials and others gathered Friday and marched from a rally in Harlem to a police precinct.

Police say some demonstrators didn't comply with orders not to block the building's entrance and were arrested on disorderly conduct charges. Police say most of them will be given summonses and released.

Opponents say the stop-and-frisk policy unfairly targets black and Hispanic men. The police department says it's a necessary crime-fighting tool and doesn't target a particular race.

West has been arrested before at protests for causes he supports, including the Occupy Wall Street movement. He says "everybody's got a voice."
