NBC News – The fatal shooting of a 16-year-old boy by undercover police sparked a protest in New York City on Monday night.

Kimani Gray was killed in the East Flatbush area of Brooklyn on Saturday, NBCNewYork.com reported.

On Monday, a protest and candlelight vigil for Gray turned “disorderly,” according to police. A store was “ransacked” and one person was arrested.

Police say Gray was approached by two officers on Saturday because he was acting suspiciously, NBCNewYork.com reported. According to police, the officers identified themselves and only fired at Gray after he raised a .38 revolver.

However, one witness at the scene told NBCNewYork.com that he heard no warning being given.

Gray had previously been arrested four times for charges including grand larceny, according to NBCNewYork.com.
