Denver police took the passenger into custody and were interviewing him last night. "There was a disturbance onboard, an unruly passenger," Denver airport police said in a statement. "Due to that disturbance, pilots decided to divert to Denver." The man had consumed alcohol before and during the flight, said Kathy Wright, an FBI spokeswoman. After questioning, the suspect was sent for a medical evaluation.
