Third party need to prove locus standing before court that how is he aggrieved by bail.
Better way is to approach state through public prosecutor with evidence and ask him to make an application for cancellation. Because it is prerogative of public prosecutor and aggrieved or effected person to apply for cancellation of bail so it is better to contact state rather than directly going.
Though there are judgements on both side but if you directly approach then it would be difficult to prove locus standii in the matter and application may be dismissed for cancellation.
