Squirrel Attack Leaves at Least 3 Injured at Florida Senior Living Facility, According to 911 Caller "It's jumping on people and biting them," the caller told the 911 dispatcher.

 -- Think squirrels are harmless? Think again.

One of the nimble, bushy-tailed rodents went on a rampage Thursday at a senior citizens living facility in Florida, leaving three people injured and bleeding, according to a 911 call released by the Volusia County Sheriff's Office.

"We had a squirrel that entered our building, and it’s in our activity room, and it’s jumping on people and biting them and scratching them ... so we need help," says the female caller, adding that she ran into her office at Sterling Court apartments in Deltona to make the call. Delton is about 30 miles northeast of Orlando.

The frantic-sounding caller tells the dispatcher, "We need some care for people here. It’s still in there and people are bleeding."

The caller tells the 911 dispatcher that an ambulance is needed because "at least three or four, possibly more" were bitten by the squirrel.

In the background, someone is heard saying "the squirrel is still in here," while another says "I feel lightheaded! I don't feel good!"

"We need help for the people -- it's not about the squirrel," says the caller.

The dispatcher asks where the pint-sized creature is, to which the caller responds, “They told me they threw it out of the building."

According to the Orlando Sentinel, the injured "were doing fine."
