bad incident at SPL match

Nasty incident at Hearts-Celtic match. I went to one match at Tynecastle in 2008 and was struck by the understated but serious security presence (for a Cup match with Motherwell). I would have thought the security would have been a bit higher for a league match against Celtic, but apparently not.

This sort of behaviour has no place in football.
