Pakistani police say they are investigating whether a Muslim cleric who allegedly tried to frame a Christian girl for blasphemy should be charged with insulting Islam himself.

Police officer Munir Jafferi says officials registered the blasphemy case against Khalid Chisti on Monday.

Police arrested Chisti on Saturday after a member of the cleric's mosque accused him of stashing pages of a Koran in a Christian girl's bag to make it seem like she burned the Islamic holy book. He has denied the allegation.

Jafferi says Chisti could be sentenced to life in prison if he is convicted of desecrating the Koran.

The Christian girl's lawyer, Tahir Naveed Chaudhry, says his client will remain in prison until at least Friday after her bail hearing was delayed for the second time Monday.
