The weekend discovery of a partially-burnt Quran outside a Chicago mosque was followed yesterday by the discovery of hate mail. That’s according to leaders of the Muslim Community Center on the city’s North Side.

MCC Board member Dr. Mohammed Kaiseruddin says the author of the letter signed off as “The Catholic Man.” Kaiseruddin doesn’t know if it was left by the same person that deposited the burnt Quran outside the Mosque’s north entrance.

“In the letter he says ‘I have decided a long time ago to burn the unholy Quran,’” Kaiseruddin read.

The letter was found in the same place as the desecrated Quran.

MCC leaders have turned over both items to the police.

The MCC has historically enjoyed good relations with its city neighbors. But Kaiseruddin says a recent controversy over a proposed Quran burning in Florida may have inspired local copycats.
