Police initially responded to reports of a naked and bloody man jumping on someone's car.
A female driver had stopped to help at that scene along the 1100 block of Quince Road when she saw a home on fire.
Police say the suspect, identified as Zachary Pammer, forced his way into the car and assaulted the woman.
