As Addai-Nyamekye explains in the documentary "Above the Law," debuting Saturday on "CBC Docs POV" and CBC Gem, police officers in the city unlawfully detained him when his car got stuck in the snow in December 2013.
He says they drove him to a remote location and abandoned him in -28 Celsius weather in the middle of the night.
After calling 911 for help, Addai-Nyamekye says he was tasered and assaulted by a constable who came to his location and chided him for calling the emergency line.
He was left in so much pain he could barely stand, and with post-traumatic stress disorder that continues to this day.
Addai-Nyamekye was charged with assaulting a police officer in the incident but was later acquitted after a judge saw video, taken from a police helicopter, showing him being beaten and dragged while handcuffed through the snow by an officer.
He got no compensation, but amid the release of the documentary and a global movement against systemic racism and police brutality, he says he's happy to finally see some attention on cases like his.
