Celtic boss Neil Lennon has praised his captain Scott Brown for his reaction to a Rangers supporter taunting the death of his late sister.
Brown was leaving Ibrox after Celtic's 2-0 win over the rivals when the incident occurred. The remarks were widely condemned by Rangers fans both at the time and later on social media, with the individual involved subsequently banned from attending football matches for life.
Brown's sister Fiona passed away at the age of 21 in 2008 after a battle with skin cancer.
Lennon was speaking to members of the media ahead of Celtic's game against Hamilton at the weekend, and he praised the way his player reacted to the shocking remark.
I've had a brief chat with him about it and I think he handled the situation very well.
It's incredibly hard (not to react). I don't know what I would have done. I'm older now and Scott is a lot more mature. Maybe five or six years ago it might have been a different outcome.
I'm not sure what that lad was trying to prove or what his thought process was, if he had one at all. It's disgusting.
I think it's awful, horrendous. To even think about that, let alone say it, is horrendous.
I applaud Rangers for the swift action they took and the support a lot of their fans have given to Scott but it's got to stop. There's no call for that.
Lennon believes that while abuse has always been a part of football in some way, the problem seems to be getting worse.
He links this with the current political climate in Britain, especially when it comes to racist incidents.
We're talking not only here, in Britain now there seems to be this uprising in a lot of racism again. It's rearing its ugly head.
We have a sectarian problem here, we know that.
Ninety five per cent of supporters are really good and, like Scott said, he doesn't mind during the game, but when we're out and about on the streets trying to live our lives, we are not in a football ground. They have no right to abuse or insult people in that manner.
