This is probably not what the Suffolk school system has in mind when it designs after-school programs.

When police received a report about suspicious subjects around the doors of mobile classrooms at Kilby Shores Elementary School at about 6:30 p.m. Thursday, they found two juveniles on the scene.

One was running from a classroom. The other was hiding under a desk.

The mobile classrooms have been the target of several burglaries and vandalisms during the past few weeks, and police were quick to respond to the school once they received the call.

An investigation revealed that the two had entered or damaged four classrooms, according to Suffolk spokeswoman Debbie George, who said in a press release that the pair also had been connected to several of the previous burglaries and vandalisms.

Police will be obtaining juvenile petitions for the 15-year-old boys, according to George.
