Unruly passenger forces flight to make emergency landing

The suspect allegedly threatened passengers.

In an incident of mid-air ruckus, a passenger aboard an American Airlines flight started punching seats, yelling and smoking, forcing the pilot to make an emergency landing.
American Flight 2408 from Phoenix to Minneapolis was diverted to Denver on Friday after the unruly  passenger's disruptive behavior continued for around 20 minutes.
According to a CNN report, just an hour after takeoff the man created ruckus and began yelling and threatening other passengers. 
"He punched the seat in front of him and the lady screamed," a passenger Jim Dickey said, adding that he went to the lavatory where he started smoking a cigarette.
That's when some passengers began preparing themselves to restrain the man physically. "The guy right behind me switched seats to the aisle in case things went awry," Dickey added.
Upon landing in Denver, the man was removed from the plane and arrested at the airport. American Airlines confirmed the incident and said in a statement: 'Law enforcement met the flight, and the aircraft re-departed. Thank you to our crew members for taking care of our customers during this situation'.
