A Florida man carrying a pocket knife his bicycle onto a high school campus, walked into a classroom and sat down with students.

Derek Marlowe, 51, reportedly evaded the campus monitor who would check vehicles coming into Spruce Creek High School in Port Orange, Fla., says a news report. After he got through, school staff inside the building were alerted.

He was spotted on surveillance camera entering the school hallway where he stood for a short while, before walking into a classroom. 

A Click Orange report said that the classroom's teacher activated his emergency button located in his classroom, which sent assistance to the classroom immediately.

The school was not placed on lockdown and there was no "code red" call made.

He was charged with trespassing on school grounds, campus disruption and disorderly conduct.
