Matthew Schwertfeger, 28, of New Lenox was taken into custody Friday on charges of stalking, obscenity, intimidation, possession of a controlled substance and possession of cannabis.
Two days before Schwertfeger's arrest, a woman identifying herself as his girlfriend sought a protective order against him and told of his allegedly posting their sex tape.
"Matthew posted on the Internet video of Matthew and myself having sex," Ashley Lewis, 22, wrote in her petition for the protective order.
"I did not know he had such a tape," Lewis wrote. "He also posted personal information about me."
Lewis said she informed the police about the tape on Jan. 24. She also detailed an alleged August incident involving Schwertfeger.
"Matthew came to my house at night, kicked in a window trying to get into the house and kicked my car, putting a dent into it," Lewis wrote. "I called the police and Matthew left before the police got to my house. It had been a year since I broke up with him."
Lewis went on to describe how she lives in fear of Schwertfeger.
"I am afraid of Matthew because of his temper," she wrote in her petition. "With me pressing charges against him I know he will be angry and I fear he will come after me. I am afraid he will come back to my job. I fear for my safety."
Lewis also wrote she now plans to change her name.
The New Lenox police did not immediately respond to an inquiry about the case.
In her petition, Lewis wrote that Schwertfeger lives on Churchill Drive but jail records list his address as a residence on Nelson Road.
The New Lenox police once arrested both Schwertfeger and Lewis together after an alleged scuffle over another woman. Schwertfeger was charged with battery and resisting arrest in connection with the November 2011 incident. Lewis was charged with battery and criminal property damage.
Lewis had shown up with a friend at Schwertfeger's place to confront him about the other woman, police said at the time. She reportedly arrived in time to find him in a car with the third side of the apparent love triangle.
Schwertfeger allegedly grabbed Lewis's friend's hair and repeatedly punched her in the face. Lewis countered by yanking the hair of the woman in the car and punching her, according to police. She also allegedly managed to damage an arm rest in the car.
Prosecutors eventually dropped the charges against both Schwertfeger and Lewis.
