There's a streamer that caught almost all of it, I can't tell why the cops tried to arrest a guy but it looks like he got away from them.https://t.co/Tkmyy5eb9V pic.twitter.com/KXa0xzB9wy

Three people were arrested and just taken away from the War Memorial by police. I couldn’t see what happened that led to the arrested but a good twenty cops bolted forward to arrest these three people #cdnpoli pic.twitter.com/lUYcuTGOpV
