A police officer is being accused of knocking out a teenager during a stop in Clinton Hill.
According to a Brooklyn paper, Marcel Hamer was walking home from school smoking a cigarette when a plainclothes cop got out of his car and accused him of smoking marijuana.
The law firm Ross & Hill has released cellphone video of the alleged incident.
The 17-year-old's parents claim that the officer punched their son while trying to arrest him, and say he suffered brain damage as a result.
