Editor's Note: There was some confusion over the aggressive nature of the fox. Police Chief Robert Noble cleared up that the fox was aggressive in at least two of the three reported incidents. A clarification will also be printed in next week's edition of Yorktown News.

YORKTOWN, N.Y. – Three people in Yorktown were bitten or scratched over the weekend by a fox, prompting the Westchester County Health Department to issue a rabies advisory on Tuesday.

The first attack occurred at 6 a.m. Saturday, when a jogger was bitten by a fox on Lee Boulevard. A second man was bitten in his backyard on North Deerfield Road at 8:30 a.m. that same day, and a woman was bitten in her backyard at 12:30 p.m. Sunday.

The county said that “due to its aggressive behavior, the fox is believed to be rabid.” All three people who were bitten received preventative rabies treatment, the county added.

In at least two of these instances, the fox was the clear aggressor and bit people who were “minding their own business,” said Police Chief Robert Noble.

“One person was jogging and another subject was taking care of his pool in his backyard when they were unexpectedly bitten,” Noble said.

The county said it has robocalled residents, alerting them to the potentially rabid fox. Though it’s possible the fox is rabid, said Lt. Tom Gentner, there is not enough information to make that determination.

“We’re not saying it is or it isn’t,” he said.

The Yorktown Police Department has reached out to both the New York State Department of Environmental Conservation and a private trapper.

“We are definitely monitoring the situation,” Gentner said.

Residents are advised not to approach the fox if they see it.

“If they see a fox and it’s acting aggressive or peculiar, they should call the authorities,” Gentner said.

Westchester County Health Commissioner Sherlita Amler advised residents to “stay alert and closely supervise children and pets when outside.”
