Another riot occurred in August 1992 at Montreal's Olympic Stadium, during a co-headlining tour with Metallica. Prior to Guns N' Roses' appearance, Metallica's set was cut short after singer-guitarist James Hetfield suffered second-degree burns in a pyrotechnics accident. However, Guns N' Roses was unable to go on stage early, because Rose once again was late arriving at the venue. Nearly an hour into their show, Rose complained of voice problems before walking off stage, following which a riot erupted in downtown Montreal, resulting in an estimated $400,000 in damages. In November of that year, Rose was convicted of property damage and assault in relation to the Riverport riot; he was fined $50,000 and received two years' probation.
