Twenty-four-year-old Joseph Nicholson was arraigned Thursday on charges including indecent assault and corruption of minors. Nicholson is a former janitor at Downingtown West High School, about 30 miles west of Philadelphia.
Authorities say Nicholson kissed and touched one girl and told her and another girl he wanted to have sex with them.
Nicholson was charged last month with having sex with another 15-year-old girl. He faces charges including aggravated indecent assault and statutory sexual assault in that case.
Nicholson's attorney, John L. Lachall, declined comment on the latest charges.
