As if the rampant sign vandalism wasn’t enough, the Associated Press reports that three recent bathroom fires inside bathrooms at the recently renovated Woodrow Wilson High School have caused $150,000 in damages.

According to Wilson Principal Pete Cahall, the fires were set by students who aren’t treating the sparkling new facility with the respect it deserves:

Cahall said he is recommending expulsion for the four students as well as “pressing for the most severe criminal charges.” He also said he will make every effort to recover clean-up and repair costs from those responsible.

He added that security cameras have been “repositioned” for clear views of the entrances to all restrooms, and that security has been ordered to monitor the cameras at all times.

Cahall warned students: “Even if you are not directly involved in a situation and can be put at the place and time of an incident and you do nothing to be a part of the solution, you will be held accountable for whatever occurred. In other words, you are either part of the problem or solution.”

Wilson, which was built in 1935, reopened this year after undergoing a lengthy $115 million modernization. The school was added to the National Register of Historic Places in 2010.
