On June 25, 2011, police dog Czar (pictured) responded to a call with Sgt. James Walsh and Officer Frank Reda, Czar's handler, about a man with a knife on Chandler Street in Norwalk, Conn. They arrived to find four men, Jose Salamayor, 22, Jose Morales, 25, Luis Oliva, 27, and David Oliva, 20, armed with knives ganging up on one man, defending himself with a hammer. While Walsh chased Oliva, Reda engaged Salamayor in what The Daily Norwalk reported as "hand to hand combat in defense of the suspect's aggressive attack with two knives." When Czar intervened, the man attacked the dog inflicting wounds to his head and stabbing the dog through the tongue. Czar got his man anyway, and according to Norwalk Police Sgt. Andre Velez the courageous animal, "probably saved the life of Officer Reda by engaging the armed suspect, who had two knives. The dog suffered numerous cuts to the head area and never abandoned his defense of Officer Reda." Had Reda been alone, he would have had to use deadly force to defend himself. The four assailants were arrested for breach of peace, interfering with an officer, conspiracy, criminal attempt, assault and carrying a dangerous weapon. Salamayor, who was treated for his injuries at a hospital after his fight with Czar, was also charged with cruelty to animals and assault on a police officer. Oliva was also charged with assault on a police officer.
