HAMILTON, N.J., Jan. 31 (UPI) -- A civilian New Jersey State Police employee has been charged with sneaking into his church at night to use a nun's computer to view online pornography.

Thomas Findler was arrested early Wednesday at Grace-St. Paul Episcopal Church in Hamilton, just outside the state capital, Trenton, the Philadelphia Inquirer reported Thursday. A custodian flagged down a police car after finding Findler on the nun's computer.

Lt. James Kostoplis, a police detective, said Findler had copies of keys to the church in his possession when he was arrested. Church officials had become aware that someone was using a computer after hours to access pornographic Web sites, the detective added.

Findler, who has worked as a state police clerk for several years, was charged with burglary, theft and theft of services.
