Police charged a man from Carlton North with six counts of assaulting police as well as abusing an animal. They allege he used a liquid irritant against four police officers on foot and another on horseback, who also received a load of horse manure.

Police charged another protester from Templestowe Lower with four counts of obstructing police and two counts of abusing an animal. A third man from Yarraville also stands charged with assaulting police, as well as tormenting/abusing an animal, intentionally obstructing police and discharging a missile.

Police obtained a search warrant to enter the home of a Mount Waverly and charged him with two counts of animal abuse and one of obstructing police and theft. While charging the man they also arrested a 22-year-old woman who was also found at the house, reportedly for growing marijuana.
