The heroic efforts of a young Dakabin family in the middle of the night could well have saved the life of a terrified woman running from a knife-wielding man.

Dakabin dad Chris Weston and his partner opened their door to the desperate woman as she fled what is believed to be a domestic violence attack from a man who was armed with several knives outside homes on Surround St around midnight.

Neighbours listened on as the man carried on however it's believed the Weston family was able to give the woman shelter in their home as police rushed to the scene.

"A lady's life was saved," Mr Weston posted to Facebook today.

"I will add that my partner and our girls as well were amazing.

"Absolutely terrifying situation we've been involved in (sic).

"Fair to say we could have all been injured or killed for helping save someone.

"We are however safe and well including the lady we protected due to some quick thinking on my partner's behalf, and the actions of the QPS."

Neighbours reported the woman had run from door to door seeking refuge after the man slashed her legs.

The man, 27, was later shot dead by police after tasers did not stop him confronting them while still armed.
