The police came under fire after images appeared in which an officer repeatedly struck demonstrators with a baton.
Ugly fighting ensued when climate change activists blocked disabled access to the Melbourne Convention Center and had to be physically removed on Tuesday.
Video footage showed demonstrators who slowly walked away from the door according to police requests.
A woman in a blue sweater raised her hands as she walked away and was repeatedly beaten on her back. Other protesters were also pushed out of the way.

Some social media users expressed their outrage at the eight-second clip that was shared on Twitter, with one that labeled police actions as & # 39; unnecessary harshness & # 39 ;.
Another person wrote: & # 39; The woman literally puts her hands in submission and is then beaten by an overly aggressive police officer with small man syndrome. & # 39;
Another said that there is & # 39; not much evidence & # 39; was to justify the use of the baton.
Others wondered if the short clip showed the whole story.
Others wondered if the short clip showed the whole story. They even blamed the demonstrators
A social media user said: & # 39; I only saw one agent with a baton … interesting to see if there were other angles. & # 39;
One person blamed the demonstrators for their actions.
& # 39; Should not have simply blocked the joint. Continue is not an obstacle. Protest "peacefully", & the person wrote.
A Victoria Police spokesperson told Daily Mail Australia: “Victoria Police is aware of various videos circulating about police use of force during today's demonstration.
& # 39; The images are evaluated to ensure that all officers' actions were a response to the illegal activities of the demonstrators and in accordance with the training.
& # 39; However, no formal complaints were received, after viewing the images if misconduct has been established, the matter is referred to the Professional Standards Command. & # 39;
More than 20 protesters against climate change were arrested Tuesday morning when they focused on the mine conference.
Photos showed a man with dreadlocks and red shorts desperately resisting officers, while the images captured several police officers dragging a man away from the face while others were using capsicum spray on demonstrators.
Two of the protesters were arrested for alleged animal abuse after a police horse was attacked, Victoria Police said.

Reaction of miners to protests
Organizers say the protest action is based on misconceptions about the mining industry.
& # 39; There is a misconception that if an mining industry does not work with sustainable principles in mind & # 39 ;, they said in a statement.
Mining is vital for the production of electricity, solar panels, batteries for electric cars, pacemakers and medical equipment and public transportation, they said.
This year, the conference will examine the importance of battery minerals used in the emerging market for electric cars and the growing importance of ethical investments for resource companies.
Activists picked up the center at multiple entrances and sang & # 39; land rights, not mining rights & # 39 ;, closed IMARC and & # 39; blood on your hands & # 39; while pushing back on a police line.
A Victoria Police spokesperson said: & The police have arrested more than 20 demonstrators outside the Melbourne Convention and Exhibition Center.
& # 39; The protesters blocked the disabled and wheelchair access to the building and were asked to move but refused. The police withdrew and the protesters were arrested.
& # 39; One police officer was slightly injured during an arrest and receives medical treatment on the spot. & # 39;
The international mining and resource conference began on Tuesday and will receive thousands of delegates from all over the world throughout the week.
Police say 11 different groups are planning to & # 39; maximum disruption & # 39; outside the conference, with protests likely to cross parts of the CBD.
More than 300 police officers will be assigned every day to ensure that activists do not violate the law or adversely affect the community.
The Extinction Rebellion group organized a week of climate protests early this month and Victoria Command commander Tim Tully said activists could step up their methods this time.
& # 39; We expect increased tactics from the protest groups & # 39 ;, he told reporters in Melbourne on Monday.
& # 39; Our intelligence suggests that the demonstrators have planned, and are well coordinated, to undertake different tactics than what we saw, or very similar tactics to what we saw in recent protest activity.

A spokeswoman for one of the groups, IMARC Alliance, said they have no intention of causing damage in the CBD.
& # 39; Our intention has never been to disrupt the city … we want to end the conference with blocking tactics, & # 39; Emma Black told 3AW.
& # 39; Our enemy is not a motorist or the police, our enemies are the business leaders for mining. & # 39;
But her group cannot control Extinction Rebellion, she said.
Acting Commander Tully said protest groups were unwilling to give the police a good idea of what to expect.

& # 39; It was very frustrating, the lack of involvement we have had, & # 39; he said.
A statement from the conference organizers said they welcomed the right of the demonstrators to express their views, & # 39; but not to cause disruption & # 39 ;.
"Just as outsiders have the right to protest peacefully, the 7,000 experts from around the world have the right to meet to discuss mining," a spokesperson said.
Victorian opposition leader Michael O & # 39; Brien said that people should be able to do their business without being confronted with & # 39; constant demonstrations & # 39 ;.
& # 39; It makes Melbourne a joke and unless the prime minister starts giving the police the powers they need to do with it, it just goes on and on & he says to reporters.
The conference on mining and resources is scheduled for three days.
