A Maine man who was dragged out of his tent and attacked by a polar bear in a Canadian national park continues to improve at a hospital in Montreal.
Matthew Dyer of Turner, a lawyer for Pine Tree Legal Assistance in Lewiston, was airlifted for treatment after the bear broke through an electrified fence and attacked him early Tuesday.
Dyer's fellow campers drove the bear off with signal flares.
A hospital spokeswoman told the Portland Press Herald that Dyer was in critical but stable condition and showing signs of progress Sunday.
Dyer was attacked in Torngat Mountains National Park at the northern tip of Labrador. A Parks Canada spokesman says the eight-person group was advised to hire an armed polar bear guard but decided against the safety measure.
