BALTIMORE (WJZ) — Johns Hopkins University fired an associate research professor over a confrontation he had with students participating in a sit-in on campus.

According to a letter written for faculty, professor Daniel Povey was reportedly terminated for jeopardizing student safety.

Povey was initially placed on administrative leave in May when he used bolt cutters to enter a building and access computer servers hosting his research.

Students, who had occupied the building for weeks, were protesting legislation that would allow Hopkins to create an armed campus police force.
