Police say it happened near the St. Mary Magdalene Catholic School in Apex.
Calven Michael Gallimore, 20, was arrested on March 16 and charged with multiple counts of indecent exposure.
According to police, four students were looking out a second story window at the school on March 1 and spotted Gallimore, exposing himself on a bench just outside the school's front door.
It happened just days after he bonded out of jail in a similar case.
He was in jail on indecent exposure charges stemming from a Feb. 15 incident at the TJ Maxx at Beaver Creek Commons in which he exposed himself to a 39-year-old woman.
"We've already locked him up one time for indecent exposure and then he turns around and does it again before he even goes to court on the first offense," Apex Police Capt. Ann Stephens told ABC11 on Monday. "So obviously that's a concern to us. But it's a great way for the community to know when they see something to call immediately don't wait until they get home, don't wait two or three days later, to always call right then so an officer can respond."
