Joseph Coy already faced charges of third-degree assault, bias-motivated crime and obstructing a peace officer when he appeared in a Boulder County courtroom Monday morning. A second-degree assault charge was added after medical records on Coy's alleged victim, Olubiyi Ogundipe, showed his injuries were more serious than first thought.
Coy's case is scheduled for a preliminary hearing at 9 a.m. Nov. 17.
Zachrey Harris, 21, also was arrested on suspicion of harassment and bias-motivated crime in connection with the Sept.
His case is set for a pre-trial conference Nov. 24.
Coy and Harris are suspected of punching University of Colorado student Ogundipe in the face after calling him and another man from Nigeria "monkeys" and other racial slurs, police reported.
Witnesses said Harris appeared to be the main person using racist terms, according to an arrest affidavit. He's suspected of telling Ogundipe and his friend, Ahmad Abdulkareem, to "go back to your country," according to the affidavit.
A CU police officer who was driving by the altercation said she saw someone, later identified as Coy, punching Ogundipe and pulled over to intervene.
