The young lad was about 10/11 years old. There was a lot of finger pointing going on and the "biter" left his seat and came in to the aisle, still finger pointing. Then made his was back to his seat -the "victim" was on the row behind him. He reached up and grabbed his face and pulled it towards him. Bizarrely, I thought he was giving him a drunken kiss as a peace offering! Realised he was then biting his nose!! Nothing then seemed to happen and the biter stayed where he was (right next to away fans) 2 Stewards then came down and escorted him out. His lad was in tears.So it’s hearsay then.
Also had to tell this chap to put his coat on.
