In 2000, after being sent off during an Old Firm match, Rangers midfielder Barry Ferguson was involved in a violent brawl with Celtic fans at a hotel later in the same evening;[65] a year later, Ferguson (by now club captain) was sitting in the stand when he appeared to throw ice packs towards the Celtic dugout after Rangers conceded a late goal, however the referee missed the incident and no action was taken.[66] In that same match, a Celtic supporter was photographed making an 'aeroplane' gesture towards American Rangers player Claudio Reyna a few weeks after the September 11 attacks.[66] A 2004 match at Ibrox which "descended into even more mayhem and madness than usual" led to a police enquiry over the conduct of the players and staff.[67][68]
