A Kentucky grandmother was arrested after she snuck into a high school and scattered naked photos of a woman on the school’s property.

Police said Frances Joyce Bailey entered Pleasure Ridge Park High School in Louisville earlier this month and left the explicit pictures in the girls’ restroom and on the grass next to a parking lot. Authorities told local media Bailey, 60, gained access to the school by following two girls who had been buzzed in.

According to the outlet, the woman in the photos has a child at the school. Police said the woman is also the ex-girlfriend of Bailey’s son and had recently filed an emergency protective order against him.

Bailey allegedly said she found the photos on her son’s phone.

A spokesperson for the school district said the images were on the property “for just a few minutes.”

“As soon as students saw them – they took them all down and immediately went to administrators,” the statement read. “The incident was caught on videotape and PRP leadership worked with police during the investigation. We have reiterated our school protocols to students and reminded them that they are not to let anyone inside the building.”

Bailey was charged with distribution of obscene matter, criminal trespassing and harassment. She’s currently being held at the Jefferson County Jail.
