Two police officers have been injured, one seriously, in a brawl involving up to 80 people, in Western Australia.
The constables had been called to a family brawl in the northern town of Wyndham just before 2am (local time) on Friday.
When they arrested one person, about 20 people turned on the officers, striking them both on the head.
The crowd also attacked a police car, smashing its windows.
The ABC reports the officers released the man for their own protection before retreating.
They went to Wyndham hospital for treatment, where one officer was found to have serious facial injuries. He is being flown to Perth for treatment.
