Interesting... do note how no one was arrested on charges of blasphemy but then when the Quran is defiled something happens in the bum of mullahs and they begin ranting. This is a classic example of laws being used and applied selectively. In either case I do not think the issue between Sikh and Hindu community should have been complicated further with allegations of blasphemy.
But still its a point to ponder. Blasphemy law applies only to insults against Muslims but why does it not apply when a muslim gardener calls a Christian a ***** or something else? Law is selectively being applied here.
