Polar bear crosses electric fence, mauls US hiker camping in Canadian park

From CBC News: A Maine man hiking with a group in a northeastern Canadian national park was dragged from his tent and mauled by a polar bear last week, despite the fact that their encampment was surrounded by an electric fence.

Dyer was mauled by the bear but was dropped after the other group members fired flares to scare the bear off. 

Jeanne Wells, Dyer's wife, said in a statement that she's grateful for the help he's received.

"My husband is in critical but stable condition; he is a strong man and he is making improvements every day," she said. 

Dyer's group had not hired an armed Inuit guard against bears, as recommended by Parks Canada.
