UEFA has charged both Inter Milan and Celtic after an incident during their Europa League fixture on Thursday night.
Fireworks were let off by both sets of supporters during the game at San Siro, and UEFA has wasted little time in handing charges to both clubs.
A hearing has been scheduled for March 19, but the charge for Celtic is significant after they were fined £7,300 on Wednesday for a similar offence against Dinamo Zagreb.
The game ended 1-0 to Inter, who progressed to the last 16 after securing a 4-3 aggregate success over the Scottish Premiership leaders.
