Before he even boarded the plane, Anil Uskanil had been arrested by police at Los Angeles International Airport after a worker allegedly spotted him walking through a security door leading from the terminal to an airfield ramp shortly before 3 a.m Friday. He was released after being charged with a misdemeanor, police said.
He later boarded American Airlines Flight 31, but looked disheveled and "clearly out of place," passenger Donna Basden told the Associated Press.
Basden said that when she and her companion sat down in their first-class seats, they found a laptop computer in the seat-back pocket. A flight attendant said the computer probably belonged to a man had left it there and gone to the bathroom, according to Basden.
Uskanil retrieved the laptop - scowling, Basden's companion said.
Uskanil reportedly tried to then sit in a different first-class seat, but he was eventually directed to his seat at the back of the plane.
Halfway through the flight, around 9:30 a.m., according to an FBI agent, Uskanil again appeared in the front of the plane with his laptop. This time, passengers said, had a towel or blanket over his head.
"He was very quiet, moving very sluggish," passenger Grant Arakelian said, according to the Associated Press. "He was trying to approach the cabin, like where the captain is."
Uskanil's intentions were unclear, an FBI agent later told reporters. But intelligence officials have been on alert after warnings of possible terrorists group efforts to hide bombs in laptop computers and other electronic devices. Laptop computers have been banned from carry-on baggage on many U.S.-bound flights from the Middle East, and they may soon be banned on flights from Europe.
A flight attendant ran down the aisle with a beverage cart, using it to block Uskanil from the front of the plane.
"She jammed the cart in the doorway and she just said, 'You're not coming in here,'" passenger Lee Lorenzen told the Associated Press.
Lorenzen was among several passengers, including an off-duty police officer, who tried to restrain the man.
"He was pushing against the cart and a bunch of guys grabbed him," he told Hawaii News Now. "They found some duct tape. There were pillows and blankets. And they taped him to his chair."
Reports of Uskanil's behavior on the plane prompted two F-22 Raptor fighter jets to scramble.The escort was in accordance with security procedures, a Navy commander told CNBC.
After the plane landed in Honolulu, a passenger took video of FBI agents leading Uskanil, a Turkish national, off in handcuffs. Agents and police dogs then searched every seat and passenger.
The cockpit was never breached and bomb technicians found nothing threatening in Uskanil's possessions, according to the FBI. He was taken for medical evaluation, and faces a complaint for interfering with a flight crew.
The Department of Homeland Security is involved in the investigation, and agency officials said all U.S. flights would be monitored after the incident, "out of an abundance of caution."
American Airlines did not provide more information on the incident, and it's unclear if Uskanil has a lawyer. The FBI did not respond to questions, and it was unclear if he was still detained.
