It was just supposed your typical prank by the seniors at East Paulding High School.

But instead of sitting in class, 19 students have spent time sitting in jail for a stunt they pulled early Sunday morning, police said.

Authorites think at least 27 seniors are involved. The group broke into more than 100 locations on campus to spray-paint their calling card -- “Seniors 2012.”

“We’ve had senior pranks plenty of times,” East Paulding assistant principal Greg Musgrove told Channel 2 Action News, “but nothing to where this much damage has been done.”

Authorities said the vandalized windows, walls, sidewalks, signs, roadways, a school maintenance vehicle and even the entrance to a subdivision across the street.

“All those that we can ascertain that were here and involved will have some school-issued punishment for sure,” Musgrove said.

But they will also face police-issued punishment as well. The group faces criminal charges for damaging school property. Police and have not released any of the students’ names.

School system employees spent much of the day Sunday cleaning up the graffiti.
