Police used capsicum spray on the protesters, who at times pelted officers with bottles. Up to 500 people stormed through the city, working their way through Pitt Street before moving to Hyde Park amid a heavy police presence. The protesters were pushed back as police dogs were deployed and capsicum spray was used.

There is not going to be any more violence. "Our anger and emotion is purely for Allah and his message," he said. Abdullah Sary, a speaker at the protest, said the protesters came in peace and were disappointed police used tear gas and the dog squad. "The anger comes from the fact if you attack the prophet you are attacking our way of life," he told Fairfax Media.

"This was a non-violent protest but people don't like seeing their brothers attacks by dogs and ending up in hospital." A speaker said to the protesters: "The person who made this video must be held responsible." He received a loud cheer amid chants of "Allahu Akbar". Late in the afternoon a lone man from outside the group shouted: "Shame on you for promoting murder in the name of religion." The crowd swarmed at him attacking him and sparking a second wave of violent clashes with police. Police rushed to the man's aide and dragged him out of the park under a rain of waterbottles, sticks and abuse.

Founder of the Islamic Friendship Association of Australia, Keysar Trad, condemned the violent protests, describing the marchers as a noisy minority. "To be honest I am dumbfounded as to why people would deal with this issue in this particular way," he said. "It's counterproductive and does nothing to uphold the prophet's honour as they claim. In fact it does the exact opposite." The US embassy in Australia has refused to comment on whether any preparations were being made to beef up its security. The Australian Federal Police provides protection for local embassies. The Department of Foreign Affairs and Trading said it was reviewing its security arrangements for Australian embassies overseas.
