University of Central Florida officials will place on administrative leave an assistant political science professor charged this week with 138 counts of possession of child pornography.

UCF police on Monday afternoon arrested Michael S. Reichert, 37, of Oviedo, following an investigation that began when employees in the computer services division reported receiving a hard drive from Reichert with pornographic child images, according to UCF officials.

Reichert started working at UCF in 2002 and did not have a contract to teach this summer, said UCF spokesman Chad Binette.
