A review of a Poughkeepsie man's computers turned up "numerous pornographic images which involved children," State Police said Tuesday, a day after arresting the man.

Investigators arrested 24-year-old Jeremy Simpson on Monday and seized "multiple digital devices" from his home on Van Wagner Road.

The investigation was prompted by a tip, although police did not say how they received the tip or how the tipster knew Simpson allegedly was trading child pornography on the Internet.

A "preliminary" search of the devices turned up the child pornography, cops said, and members of the State Police computer crimes unit will conduct a complete search of the seized hard drives.

Simpson was charged with promoting a sexual performance by a child, a felony, and was back in court Tuesday afternoon for a preliminary hearing after he was arraigned on Monday. Simpson was returned to Dutchess County Jail, where he was held in lieu of $25,000 bail or $50,000 bond. Simpson did not have an attorney listed in court records as of Tuesday evening.

Police are still looking into Simpson's activities and other possible child pornography cases in the local area. Anyone with information on those cases can call 845-677-7300.
