The boy, whose name has not been released because he is a juvenile, got into a "verbal exchange" with the 60-year-old victim before shooting him on the bus in southwest Denver on Jan. 27, police said in a statement.

A second person suffered minor injuries that did not require hospitalization.

The suspect was arrested Thursday and was being held for investigation on suspicion of first-degree murder.

No other information was released, and the probable cause statement was not publicly available because the suspect is a minor.
