MILWAUKEE (CBS 58) -- Classes were canceled at Pius XI Catholic High School on Monday, Nov. 4, and students were sent home after threatening graffiti was discovered.

In a statement, the school reported that its administration and security staff found "graffiti of a threatening nature" on the front entrance of the building. The Milwaukee Police Department was notified and is investigating.

A grandmother of one student told CBS 58 that she was taking her grandchild to the bus stop when she saw police and students leaving or being picked up.

"It’s scary: not only sad, it’s scary. I have little ones out here getting on the bus, and this is a whole high school, so it’s definitely scary," she said.

In a letter to parents and guardians, school principal Ryan Krienke said that the "inexcusable threats and destruction of property" at the school took place at around 12:50 a.m. on Monday. He asked parents and students to submit any information they might have about a person who was reportedly recorded at the school from that time.

Krienke asked people to look at the pictures and note the distinctive bike, as well as the orange ski mask and gray hoodie. He also mentioned that shoes may be covered in paint, and suggested parents consider if their children were home from midnight through 1:30 a.m.

Students who were already inside the school had their bags checked. The Milwaukee Police Department is continuing its investigation.
