A seventh-grade student who attends Pennsylvania's Wendover Middle School called police at 2:30 a.m. Wednesday to inform them he was inside the school, reports The Associated Press.
Authorities say the student had been sleepwalking and entered the school through a window. Police also said he walked around for about 15 minutes before he woke up. The student apparently lives 4 miles from the school.
Due to security concerns, the school district canceled classes Wednesday.
