A child psychologist at a Long Island preschool admitted yesterday that he paid for kiddie porn and stored it on his home and office computers, authorities said.
Peter Mies, 57, of Northport was arrested and promptly pleaded guilty to child-porn possession as part of a prearranged deal with prosecutors.

In May, cops found videos and photos on Mies' computers of kids performing sex acts. He was fired from his post at Building Blocks Developmental Preschool in Commack.

Mies has forfeited his license to practice psychology and cannot reapply for his license until after he serves 10 years' probation, officials said. He also must register as a sex offender.
