Search: Woman attacked by otter while swimming

Triathlete Leah Prudhomme, 33, blogged about an apparent run-in she had with an otter during a night swim at a Minnesota lake.  Prudhomme says the animal attacked and bit her (how many times?) while she was swimming (where was she bitten?).  She says she couldn't see the otter because it was so dark, but her wetsuit has claw marks and chunks missing.  She was later rescued and taken to the hospital (what was she treated for?).
