Two police officers were assaulted and another suffered a broken leg during two separate incidents in Canberra early on Saturday morning.

About 1.50am on Saturday police were arresting a man believed to have damaged property during a disturbance in McKellar when he allegedly became aggressive and lashed out at police, kicking one officer and causing a hand injury to another.

He was charged with two counts of assaulting a frontline community service provider, as well as resisting a territory public official and property damage.

At around 3am, police were separating an arguing couple outside a Civic bar when the man, yelling and acting aggressively, allegedly ran at the woman.

Police say officers attempted to place the man under arrest, but both the man and woman resisted, resulting in one officer breaking his leg.

The pair were subsequently charged with resisting a territory public official. The man was also charged with breaching the peace.
