Boxer Anthony Ogogo says he was racially abused by a fan after watching Norwich City in their Carabao Cup tie against Arsenal at Emirates Stadium.
The Canaries supporter, 28, believes he was targeted by a fellow Norwich fan who thought he was backing Arsenal in their 2-1 win on Tuesday.
Ogogo, from Lowestoft, said: “I was shocked. There’s no place for that in football or anywhere for that matter.
“In this day and age it’s disgusting. He said ‘Go back to your own country’.”
Middleweight Ogogo, who won bronze as an amateur at the 2012 London Olympics, played for Norwich City’s youth team as a schoolboy before switching to boxing.
The London-based boxer watched Tuesday’s game among home fans after his Arsenal-supporting friend let him use his ticket for the Carabao Cup fourth-round match.
