TULALIP, Wash. -

A woman who was bitten and scratched by a river otter as she pulled the animal off her grandson says the attack felt like "little knives going in."

Lelani Grove needed hundreds of stitches to her face, head and body. She may have minor damage to her right eye.

Grove and her 8-year-old grandson, Bryce Moser, were released from hospitals Friday night. She's recovering at home in Tulalip.

The boy has staples in his head and bandages on his arms and body. He told KOMO he doesn't remember much about Thursday's attack in the Pilchuck River.

Wildlife agents are still trying to trap the otter in the river near Lake Stevens. It would be relocated if it's a female with pups or killed if it's a male.
