A grandad claimed he lit a flare before an Old Firm game to show how it worked to his autistic grandson.
Archibald Smith, 58, sparked the pyrotechnic close to Celtic Park as the Hoops were due to host rivals Rangers in the Scottish Premiership evening fixture.
Smith had earlier attempted to stamp on the flare to put it out when caught by police. But, Sheriff Lindsay Wood told him that his excuse for committing the crime was "a lot of nonsense."
