Police blocked a bail request, saying that her life and that of her family would be in risk if she were released.
They might be right: Rimsha and her family are Christians, and the young girl's burning of a holy book has enraged their Muslim neighbors, who, according to RT News, are calling for her to be "burned alive."
Many Christians fled the Islamabad suburb of Mehrabad after the girl's alleged infraction became known, fearing violence.
It's been widely reported that Rimsha suffers from Down's Syndrome, but this has yet to be verified: Huffington Post UK reports doctors will release a report on her condition and will verify her age on Tuesday.
AFP reported that the cleric who originally turned her over to police, Hafiz Mohammed Khalid Chishti, is accusing Rimsha of "conspiracy," and that she "confessed what she did."
Chishti claimed his Christian neighbors had "previously caused antagonism by playing music in services at their makeshift church during Muslim prayer time."
In what may be an incident related to the ongoing religious hysteria, the mutilated body of an 11-year-old Christian boy was found in Pakistan's Punjab region last Friday, reported RT News.
A French cardinal, Jean-Louis Tauran, went on Vatican Radio last Saturday to defend the girl, claiming that she cannot read.
