SANDPOINT, Idaho -

Idaho Fish and Game officials are warning people to be careful at a northern Idaho lake because the region's otters are on the attack.

Chip Corsi, a regional supervisor with the Idaho Department of Fish and Game, said it's no laughing matter: The cute semiaquatic predators have been biting and terrorizing beachgoers at Priest Lake's Kalispell Bay.

Corsi says otters are small but fast and they're pretty capable of harming people. Attacks generally occur when people get between an otter and their pups or when they simply get too close.

The department also posted a warning on its Facebook page.

Corsi said the department tries to trap and relocate troublesome otters.
