A police officer in Hamilton had to draw her gun after a colleague's taser failed to subdue a man during an attack at the weekend.
Two officers were called to a domestic incident between a father and son on Sunday night.
The father had left the house by the time officers arrived, but returned as they were leaving and confronted them.
Police say a taser was used on the man twice, but it had little effect and an attack on both officers by the father, his son and a sibling followed.
The officers also used batons and pepper spray before drawing a gun.
All three family members were arrested, and face charges of aggravated assault and resisting police.
Both officers were bruised and one had a ruptured blood vessel in an eye.
