At 8:30 pm, a demo began at Crescent and de Maisonneuve - in addition to the usual one leaving from Émilie-Gamelin. Police made targeted arrests of individuals wearing red squares. Jaggi Singh was arrested. CUTV film crew were attacked three times. At de la Montagne and Ste-Catherine, there have been several confrontations between demonstrators and riot cops, both city and SQ. There has been clubbing and tear gassing.
Cops are there in force to protect the Grand Pricks.
