Scottish police are investigating “the misuse of fireworks” outside Celtic Park on Saturday.
The incident took place ahead of Celtic’s 6-0 victory over Livingston in the Scottish Premiership.
Both sides paid tribute to Prince Philip, who died at the age of 99 on Friday, observing a minute of silence when the fireworks were ignited.
A Scottish Police spokesperson said: “We are investigating the misuse of fireworks outside Celtic Park stadium on Saturday 10 April 2021. Investigations into the incident are ongoing.”
Celtic declined to comment on the situation.
Celtic hit Livingston for six
Celtic warmed up for next week’s Scottish Cup clash with Rangers with a 6-0 Premiership victory over Livingston at Parkhead.
First-half goals from winger James Forrest and midfielder David Turnbull had comfortably put the home side in the lead in the interval, but they really changed the style after the break.
Skipper Scott Brown’s header via Livi defender Jack Fitzwater in the 50th minute was followed by a formidable brace from Mohamed Elyounoussi and a late strike from substitute Ryan Christie.
James Forrest, recently recovered from ankle surgery, was kidnapped just ahead of time, which may be a cause for concern ahead of Ibrox’s final 16 Cup game at Ibrox, but acting boss General John Kennedy will have was encouraged by the convincing performance and thirst for goals.
