The Bend (Ore.) Bulletin Thursday said Nancy Campbell had been walking with her 8-year-old daughter earlier this week, when the llama suddenly knocked her down, and bit her.

Campbell's husband, Bill, said he was shocked when his daughter came home Monday to tell him her mother was being attacked by a raging llama.

Leaving his frightened daughter at home, Bill said he found the llama relentlessly attacking his wife.

“When I got there, it was still trying to attack Nancy and to be aggressive,” he said. “Every time she moved away, he came toward her.”

The concerned husband managed to distract the animal and eventually it was restrained by neighbors.

Local veterinarians said the llama was suffering from a rare behavioral disorder known as "berserk llama syndrome."

The Bulletin said Nancy only suffered minor bruises and bumps during the unusual encounter.
