A presumed rabid fox, who has already attacked a number of people, is on the loose in the Hudson Valley.

The Westchester County Department of Health is warning residents to be on the lookout for an aggressive fox that is likely rabid.

The fox attacked three people over the weekend in northern Westchester County.

According to ABC, a 56-year-old man was bitten early Saturday while jogging on Lee Boulevard in Yorktown Heights. Two others, who live in the same area, were attacked by the fox in their backyards.

"He came right up to my passenger side door," Emily Marino, a neighbor of a victim, told NBC. "You could tell he was rabid. His eyelids were hanging low."

The second victim was bitten around 8:30 a.m on Saturday. While a woman was bitten in her backyard just after noon on Sunday, NBC reports.

"I walked into the yard, started waving my hands to get it to leave, and it got it charging at me," Kathy Coakley told NBC. "It jumped up on me, it was on my arm, and I kind of pushed it away. Fell to the ground, but jumped right back. Kept coming at me."

All three are receiving treatment for the possible exposure to rabies.

Hudson Valley residents are urged to stay alert and closely supervise children and pets while outside. If you think you see the fox, call the police.
