A violent thug attacked a random stranger, brawled with doctors and threatened to rape female police officers within hours of being freed more than a year early from jail.
Ross Cossans started rampaging across Perth immediately after being released from the city's maximum security prison after serving just half of his sentence.
He was jailed in 2020 for a number of crimes including hurling a dog across a room after threatening to slit its throat during a domestic dispute with his partner.
