Summer is always interesting in New York City, and this year is no exception.

Between the "summer of hell" train delays that's making commuting even more of a nightmare for many, to the overall hot, humid weather this past month, the summer of 2017 has been a bit of downer.

Yes, the NYC Department of Parks and Recreation says an "unusually aggressive" squirrel has attacked five people in Brooklyn at Prospect Park. The attacks reportedly took place over the last two weeks.

The New York City Department of Health and Mental Hygiene told the press:

Four patients have been identified; a fifth, who was attacked while jogging, has not been identified. This is an isolated incident. Squirrels are rarely infected with rabies; however, based on the unusual aggressive behavior, the Health Department is acting under the assumption that the animal is rabid.

ABC New York 7 says that park officials went on four separate patrols Monday and found no aggressive squirrels.

Some officials are speculating that if the animal was rabid it could be dead by now. Be safe!
