A sickening video has captured the moment a man was brutally bashed in a Perth park after he attacked a group of Aboriginal people.
Police were called to Wellington Square around 2.30pm after reports a man was kicking over bins and abusing Aboriginal women in the park.
Footage obtained by Ten News shows the man falling to the ground before being repeatedly beaten with large sticks by a group of people.
The man is then kicked while lying on the ground as blood pours from his head.
As the man is left bloodied on the ground another group appear to come to his defence.
The injured man staggers to his feet and then confronts the Aboriginal group again.
When police arrived the man turns on officers and is tasered to the ground.
Ten News reporter Rebecca Munro said witnesses saw the man yelling racial abuse at Aboriginal people in the park before attacking an elderly man and two women.
She said the group defended themselves after he physically attacked them.
"What if that old man he pushed over... what if he killed him there on the spot?" a witness told Ten News.
"He's got a heart problem."
Police said officers were forced to taser the man, believed to be in his 40s, after he became aggressive and damaged a police car.
The man was taken to Royal Perth Hospital for treatment and observation.
He is currently assisting police in the investigation, along with other people involved.
The violent clash in the park comes on the same day former Liberal MP Michael Sutherland, who is planning to run in the upcoming City of Perth council elections, caused controversy by claiming Wellington Square needed to "cleaned up" because of on-going antisocial problems.
Mr Sutherland said locals were sick of people defecating in the park but denied his Facebook video was targeting Aboriginal people despite footage showing two Aboriginal women sitting cross-legged on the grass.
