Unruly Air Passenger Subdued With Duct Tape

ABC News' John Schriffen reports:

Newly released cellphone video shows passengers on board an international flight subduing an unruly passenger by tying him to his seat with duct tape and zip ties after he began screaming and hitting other passengers.

Thursday's Iceland Air flight from Reykjavik to New York's John F. Kennedy Airport sparked nationwide curiosity after a photo circulating on the Internet showed the passenger tied to his seat with tape and plastic restraints.

The unidentified passenger allegedly downed an entire bottle of duty-free alcohol, according to a man who posted the photo on his blog, who said the picture was taken by a friend on the flight.

The airline has accused the man of accosting and hitting people on the flight. Passengers say he even tried to choke the person next to him and screamed, "The plane is going to crash."

Passengers can be seen on the video cutting off pieces of duct tape, which were later used to subdue
