Langley Middle School was vandalized sometime last weekend, with toilet paper strewn about the classes and hallways, according to the Langley Police Department.

Langley Police Chief Randy Heston said the exact timing of the mischief was unknown, because the school was not checked until Monday, Aug. 8.

“Somebody got in and had a heyday with some TP,” Heston said.

How the perpetrator or perpetrators entered the building was a mystery. The doors and windows were examined, with no unlocked or open entries found.

Langley police are investigating.
