Rangers are warning fans against running onto the pitch after being charged by UEFA for an incident late in their win over Borussia Dortmund.
The governing body opened a case after children entered the playing area at the end of last month’s Europa League round of 16 second leg at Ibrox.
The club have now warned parents they will crack down on any youngsters running onto the pitch.
The Premiership champions also made it clear to players that they had been asked not to give their kit to anyone running onto the pitch.
A club statement read: “Rangers would like to remind fans that entering the field of play at any time is unacceptable and prohibited.
“The club have been informed by UEFA that they have opened disciplinary proceedings after Thursday’s game against Borussia Dortmund due to children entering the pitch.
“We have a zero-tolerance approach to those who invade the pitch. In particular, any parent found assisting their child onto the pitch will be subject to the club’s disciplinary policy.
“Our players have been informed that they should not provide shirts to any spectators entering the pitch.”
Rangers have reached the Europa League Round of 16 after the impressive result against the Bundesliga side and will now face Red Star Belgrade.
