"We had 600 fans there but there were 20-30 people who let the club down and embarrassed everybody," said Roche.
"The people involved are clearly identified, or they will be as they are on CCTV. They won't be allowed into our home matches and we will do our best to prevent them going to away matches. It was embarrassing.
"The bans are indefinite, we don't want these people around. It looked a lot worse than it was but it was totally unacceptable. I was in the directors' box and I was embarrassed," added Roche.
