It is the latest in a series of demonstrations that have killed at least six people.
The wave of protests spread to Sydney’s CBD this afternoon, beginning outside the United States Consulate and spreading through the city’s streets to Hyde Park.
The ABC understands the protest was sparked by a mass text message saying: “We must defend the honour of our prophet, we must act now”.
The riot squad and mounted police pushed demonstrators out of Sydney’s Hyde Park after a protest swept through the CBD this afternoon.
The crowds moved down College Street near the Museum, sparking running battles with the police, then ran down William Street.
The protests were triggered by a U.S. film, Innocence of Muslims, portraying the prophet Muhammad as a womaniser and paedophile.
Police said there were eight arrests and six officers were injured, two of whom are now in hospital. Two vehicles were also damaged.
Protesters earlier refused to leave Hyde Park until police released a handful of arrested men.
