Police have arrested a 19-year-old student in connection with a stabbing at Morgan State University that left three football players injured.

Police said Wednesday that Carlos Mars has been charged with assault and weapons charges.

The stabbing happened Tuesday afternoon when a fight broke out between two groups of students at the Baltimore-based campus. Police say two men were slashed, one across the chest and one in the back, and a third student suffered abrasions.

Charging documents show that a witness told investigators that Mars "repeatedly and aggressively" stabbed another student in the chest during a fight.

But Mars told investigators he "swung his knife around in a wild manner" to keep students away from his friend, who also was involved in the fight.

Police say Mars remains in jail.
