Two Buffalo police officers responding to a complaint about a domestic dispute at an East Side home Wednesday morning got into a fistfight while trying to control the situation, The Buffalo News has learned. Officers Cariol J. Horne and Greg M. Kwiatkowski - both on duty and in uniform - threw punches at each other on the driveway of a home on Walden Avenue near Sumner Place, according to police and witnesses. About seven citizens watched the two officers fight. During the scuffle, Horne jumped on Kwiatkowski's back, and Kwiatkowski punched her in the face, police said. Witnesses said Kwiatkowski's face was swollen and red. The fight was reportedly sparked when Horne tried to prevent Kwiatkowski from making an arrest, police sources say. Other witnesses say Kwiatkowski and a second officer were using excessive force to arrest a man by wrestling with him on the ground and beating him repeatedly with a police baton, and Horne was trying to stop him. "There were fisticuffs exchanged," Police Commissioner H. McCarthy Gipson said. "She reportedly jumped on his back and she got punched in the face . . . The officers were placed on an administrative leave with pay, and we will take the appropriate disciplinary actions against anyone determined to have acted inappropriately."
