A student was arrested after assaulting a faculty member at a Brooklyn high school this morning, school officials said.

The 17-year-old boy got into a heated dispute with Edmund Ludde, the dean at William H. Maxwell High School, as he was getting scanned at the school’s security checkpoint at 9:20 a.m., officials said.

The teen, whose name has not been released, allegedly shoved the teacher and punched him the face, officials said.

He was quickly nabbed by responding officers. Ludde was taken to Brookdale University Hospital for his injuries.

This is the second time the teen clashed with authorities. The teen also faces “administrative action” by the school, officials said.
