A University of Maryland, Baltimore County student was stabbed early Saturday in a residence hall on campus, police said.

About 6 a.m., two men who knew each other started fighting inside Erickson Hall, said Maj. Paul Dillon of the university's police department.

The student was stabbed in the arm during the fight, Dillon said. The injury is not life-threatening, he said.

Cody Kradz, 22, was arrested off campus and charged with first- and second-degree assault in the stabbing, Dillon said.

Kradz had recently withdrawn from UMBC, Dillon said. In February, Kradz was charged with concealing a dangerous weapon and carrying a dangerous weapon on school property, according to online court records.

Alcohol was involved in Saturday's incident, Dillon said.
