Oscar Knox
Little Oscar Knox, who won the hearts of the nation after a long battle against cancer has passed away.
On Friday a member of his family tweeted: "Our beautiful, amazing and much loved son Oscar James Knox gained his angel wings yesterday afternoon. Sleep tight little man."
Oscar, aged five, was first diagnosed with cancer back in November, 2011.
In April of last year he was given the 'all clear', but the disease returned in August.
When he was first diagnosed, his parents set up a Twitter account to update the public on Oscar's progress.
They successfully raised £250,000 to take Oscar to the USA where he received specialist treatment.
Oscar, from Mallusk, a Celtic fan, led the team out on to the pitch when they played Belfast side Cliftonville in a UEFA Champions league qualifier last year.
In a statement released on Friday, Glasgow Celtic FC said: "This is absolutely devastating news and our thoughts and prayers are with Oscar's parents, Stephen and Leona, and his little sister, Izzie, at this desperately sad time.
"We can't even begin to understand the pain of their loss, but I hope that there will be a small measure of consolation in knowing that there was genuine love and affection for Oscar from the Celtic Family throughout the world.
"Oscar's courage throughout his illness was truly inspirational, and it was a real pleasure for everyone at the club to meet Oscar when he was our team mascot last July."
Belfast boxer Carl Frampton, who supported Oscar throughout his brave battle, said:
"I'm kind of in shock, because with the wee man, I knew he was very, very sick, but you always expected him to get better because he is such a fighter.
"It's just heart-breaking."
