Chicago Police Horses Attacked in Stable 'Agitated' equines released by unknown vandals By Mary Papenfuss, Newser User Posted Sep 19, 2012 12:25 AM CDT 16 comments Comments Lt. Paul Bauer talks about the attack on police horses. (YouTube) (Newser) – Chicago police horses are recovering after a late night attack in their stable. Some 27 of the 30 horses were released from their stalls and at least two were sprayed in the face with a fire extinguisher or struck with the extinguisher can, reports CBS. One 20-year-old horse suffered eye swelling and another had injuries on a leg and flank. The rest were "very agitated and fearful," some "shaking," said a police spokesman. The vandals "did not enter to commit a theft. Rather, they entered to maliciously harm our horses—for what reason, I don't know," says a police spokesman. "The incident has upset a lot of people here. You can imagine the trauma" the horses endured. All are expected to fully recover, reports the Chicago Tribune.
