A woman was pulled from the Puget Sound in Seattle on Sunday after she was critically injured when a car crashed into her vehicle and sent it plunging into the water, authorities said.

The collision happened around 6 p.m. in the 1300 block of Alki Avenue Southwest in the West Seattle neighborhood, Seattle police said.

Bystanders had pulled the woman out of the water and were performing CPR by the time police arrived.

Two men had jumped into the water to break the window of the sinking car, and a neighbor retrieved a hammer to smash the glass, KING5-TV reported. A second neighbor got a ladder to help bring the woman onto land.
