Neil Lennon believes it is a "shame" the Green Brigade will be dispersed around Celtic Park after failing to listen to repeated warnings about their behaviour.

The Parkhead club issued a statement on Monday confirming it is to close section 111 of the stadium, which houses the Ultras group, known, for the most part, for banner displays and singing.

However, among other things, warnings to stop "lateral movement of spectators" and "body surfing" went unheeded and, consequently, supporters will be offered a refund on their season tickets or the chance to relocate.

The Celtic boss is in Sweden for the second leg of the club's Champions League third qualifying round against Elfsborg, looking to defend a 1-0 lead from the first game.

When asked about the issue, he said: "It is very disappointing because I think that section adds hugely to the atmosphere at the stadium.

"But there was a final warning after the Cliftonville game and that wasn't adhered to and the club have taken this decision.

"It is beyond me. It is a club decision and it is a shame it has come to this.

"There are lines of dialogue still open, so I wouldn't say this is the end, but there are rules and conditions and it is all about safety at the end of the day - that is paramount to the club."

A Celtic spokesman said on Monday the club had been left with "no option" but to take action to ensure the safety of supporters. Fans in section 111 are to be offered a refund or the chance to move seats.

At Saturday's match against Ross County, 35 seats in the section were damaged.

The club is also under investigation by Uefa following events at the match against Cliftonville, which was in the Champions League second qualifying round.
