Coyote attack in Edmonton prompts police rescue

Police used a helicopter to rescue a woman and her three dogs Thursday night in Edmonton after coyotes attacked one of the dogs while on a walk in the southwest area of the city.

The woman called 911 at 8:20 p.m. after falling down a six-metre embankment in the Riverbend/Terwillegar area while trying to save her dog.

Police used Air 1 to light the area, while tactical officers rappelled down the embankment to rescue the woman, who was unhurt.

While two of her dogs were also unhurt, the third was taken to an emergency vet clinic just before 11 p.m after being rescued from the North Saskatchewan River. 

There is no word on the dog's injuries.
