Police in Stamford said a city man bit off his cousin’s ear lobe and swallowed it during a fight over loud music. Officers charged Emilio Mendoza, 27, with first-degree assault and other crimes early Monday morning in connection with the attack on his cousin, Ruiz Clemente-Perez, 29. Clemente-Perez told police that he asked Mendoza to turn down his loud music because he had to work in the morning, but Mendoza started punching him in the head instead. During the brawl, Mendoza allegedly bit off part of Clemente-Perez’s left ear and swallowed it. Officers said Clemente-Perez was bleeding and missing part of his ear when they arrived.
