NSW Police have denied using excessive force to break up the Occupy Sydney protest, saying they acted with the "utmost professionalism".
Claims protesters were bashed and manhandled during a dawn raid on the Martin Place protest site have been "grossly exaggerated", Assistance Commissioner Mark Murdoch told reporters in Sydney.
"It was resolved very quickly, very peacefully," Mr Murdoch said.
"My officers conducted themselves with the utmost professionalism."
Forty people were arrested after police, including riot squad officers, raided the site shortly before 5am today and cleared the area of more than 100 protesters.
