ST. CHARLES – A Rockford man who was accused of committing a lewd act at a Riverside school has a record in St. Charles for committing a similar sex offense.

Lawrence E. Adamczyk, 49, of the 1600 block of Oregon Street in Rockford, was charged Saturday, accused of masturbating in the bleachers during a boys swim meet at Riverside High School. Police responded to a call at the school at 9:45 a.m. of a suspicious man walking the halls.

Adamczyk told police that he was “feeding from the energy of the school” and was aroused by boys in their swimwear who were at the swim meet, according to police reports.
