A riot broke out in East Flatbush tonight after a vigil for 16 year-old Kimani Gray, who was shot by cops when he pointed a gun at officers earlier this week, police said.

The disorderly group threw bottles and other objects at police officers and vehicles parked along Church Avenue, cops said. They also looted businesses including a Rite Aide.

“They poured in here like 40 or 50 of them. They pulled the registers off the counters, they flipped over everything. They punched me in the face. Several of them did, not just one [person.] It was insane,” said the store’s manager, Lorenzo Evans.

At least three other people were bleeding from the face after being assaulted in the store, the sources said.

The crowd went wild on the blocks surrounding the 67 precinct station house near Church Avenue and East 55 Street, cops and witnesses said.

Cops had one man in custody for disorderly conduct and there were no reports of injured officers — though the situation was still chaotic, witnesses said.
