Anger over a fatal police shooting this past weekend sparked a protest in East Flatbush Monday night, where more than 100 teens and adults marched, screamed and threw bottles.
Authorities said that dozens of police officers responded in riot gear.
Police say Kimani "Kiki" Gray, 16, pulled out a handgun and pointed it at authorities late Saturday night before two plainclothes officers fired 11 rounds.
Police say Gray had prior arrests for grand larceny and for inciting a riot.
While the teen's family continues to mourn his death, protesters appeared to have left garbage at a Rite Aid on Church Avenue and also threw debris in the streets Monday night.
City Councilman Jumaane Williams said the incident was about systemic oppression.
Williams said he has invited Mayor Michael Bloomberg and Police Commissioner Ray Kelly to walk the community with him in person.
"It's not about one shooting and the detail of that particular shooting. There's a feeling of disrespect that's gone on for many, many years. Many of us have been saying we need to engage more with the police department, engage more with the mayors. Instead of listening to us, they push back, and this is what's happening here," Williams said.
"They killing the innocent kids day by day. Every minute, every seconds, one of us is dying. When is it going to stop?" said one protester.
Police say one person was attacked during the protest and taken to the hospital.
One person was arrested and charged with disorderly conduct.
