MANCHESTER, England (AP) -- Police are searching for a Manchester United fan who bit off part of a man's ear at the Champions League final in Rome.
Greater Manchester Police made the appeal Wednesday, releasing video footage and still pictures.
Police said the 46-year-old victim had intervened during an altercation between the offender and a woman outside the Stadio Olimpico before United lost to Barcelona in May.
The victim was threatened by the offender, but the attack didn't come until they later came face-to-face again in the stadium.
Police said that "the offender saw the victim again inside the stadium and without provocation, violently attacked him."
The offender was wearing a blue United away shirt.
