During a pro-Palestine protest, Toronto police had detained/arrested what was likely a protestor. After that, a crowd began to form calling for the release of the protestor, initially 2 bicycle officers had come to support the officer that was initially on the scene. The crowd began to grow larger and larger chanting for the release of the subject before a large amount of Toronto police arrived to assist the outnumbered officers that were conducting the arrest. (To my knowledge and what I could see I believe the subject was released soon after)
