TV grab shows the Delta/Northwest Airlines Flight 253, where a Nigerian attempted to set off an explosive device on the Christmas Day, sits on the tarmac at the Detroit Metro Airport in Detroit, the United Sates, Dec. 27, 2009. A passenger onboard the Delta/Northwest Airlines Flight 253 was Sunday reported to be “verbally disruptive” when the airplane was landing, said officials. The Delta Air, who owns the Northwest Airlines, confirmed that a Nigerian man had locked himself in the airplane’s lavatory for one hour and became verbally disruptive. In response to the incident, crew members had to request emergency assistance upon arrival, asking for security personnel to remove the man from the airplane after it landed, said a spokeswoman from the airlines.
