A paramedic has been admitted to hospital after he was allegedly punched in the face and spat at by a drunken patient in the early hours of Thursday morning.

The senior officer, 44, was left with back and facial injuries following an incident that occurred after emergency services were called to a home in Epping just before 1am.

The alleged violence comes two days after a County Court judge quashed the jail sentences of two women who attacked a veteran paramedic, sparking community outrage, and is likely to further fuel support for law reforms.

Paramedics painted anti-violence messages on their ambulances on Wednesday, while both sides of government have promised to toughen laws to make it more likely that anyone found guilty of violence against ambulance officers would go to jail.
