Celtic have carried out their threat to ban adult supporters who try to enter Celtic Park with concession season tickets.The club revealed "a number of adult supporters attempted to enter the stadium using a concession season ticket" during Wednesday night's friendly match against Manchester City which ended in a 1-1 draw.

The culprits, who were caught by stewards, had their tickets confiscated and have consequently been banned from Celtic Park with no refund for the concession season tickets purchased.

A Celtic spokesperson told the club's website: "The club won't tolerate this and we will be unrelenting in our bid to stop this practice.

"These people are cheating fellow Celtic supporters and the club."

Prior to the game against Manchester City, the club announced that turnstile checks would be carried out as well as spot-checks on seats occupied by those in possession of a concession ticket, and that the strongest possible action would be taken against people in possession of an incorrect ticket.

Celtic warned that checks will continue to be carried out with "the minimum of inconvenience to genuine supporters, who will appreciate why the club is taking such action".
