Officers said they caught the four teenagers, ranging from 13 to 15 years old, crawling out of a Stripling Middle School window with backpacks, pillows and blankets about 1 a.m. Sunday, The Dallas Morning News reported Monday.

The teenagers, who were taken to a juvenile detention center on criminal trespass charges, told investigators they were trying to authenticate legends of ghosts haunting the school's third floor, police said.

Nothing was discovered stolen from the school.
