The Arriva Youth U-15s had won tickets in a UEFA-sponsored contest.
"We were having a great day until Liverpool scored," said Radford. "They started shouting at the lads as soon as they realized we were Scousers [Liverpool supporters]. They started shouting about Michael Shields and Heysel -- it was pandemonium.
"After we'd celebrated [Dirk] Kuyt's goal, we were spoken to by the stewards and told to leave the ground."
Requests to reenter the stadium were turned down as the boys wandered around outside the stadium.
"We were eventually granted access back to our mini-bus but were not allowed to leave the ground until 11 p.m.," said Radford. "By this stage, the lads were very anxious, quiet and very, very scared.
"They were stressed and because we weren't allowed back in the ground, we missed the rest of the game."
