A squirrel leapt on an old man and clawed him and his wife to such an extent that they both had to be hospitalised.
Richard Williams, 87, was cleaning his garage when the rodent started to bite him.
The rodent has also attacked eight other people in the last three weeks, in a California neighbourhood.
Speaking to Williams said CBS San Francisco, ‘He charged me and jumped, and from then on, the battle started.’
‘He was really vicious. He was clawing and scratching and I was trying to get him off.
‘Every time I’d get him off, he’d jump back up again.’
His wife Norma hit back with a broom, but it scratched her hand.
Williams then grabbed the squirrel by the tail and threw it to the floor, where it lay stunned before racing off.
