FORT LAUDERDALE, Florida (CNN) -- Former NFL star O.J. Simpson remained quiet and expressionless as he and his girlfriend brushed through a crush of reporters to an SUV early Thursday after flying in from Las Vegas, Nevada.
O.J. Simpson arrives just after midnight Thursday at the Fort Lauderdale, Florida, airport.
Video from outside Fort Lauderdale-Hollywood International Airport showed Simpson -- dressed in a gray suit, white shirt and white visor -- getting into a Ford Excursion parked curbside, just after midnight. His girlfriend, Christine Prody, was wearing sunglasses and a baseball cap.
Simpson sat in an aisle seat in economy class and smiled and nodded as other passengers took photos of him with cell phones and digital cameras, The Associated Press reported.
New York Post reporter Steve Dunleavy, who was on the same U.S. Air flight as Simpson, told reporters that "between dozing and watching the movie 'Oceans 13,' " Simpson "didn't look the least stressed. In fact, he was rather relaxed."
Simpson, 60, was free to return to his home in Miami after posting a $125,000 bond after a court hearing in a Las Vegas sports memorabilia robbery case.
Following a judge's orders, Simpson also turned over his passport to his attorneys before being released from the Clark County Detention Center.
Judge Joe Bonaventure ordered him not to have contact with any of the victims, witnesses or co-defendants connected to the alleged armed robbery in a Las Vegas hotel room last week.
Simpson faces 11 charges, including 10 felonies. The two counts of first-degree kidnapping using a deadly weapon could bring a sentence of life in prison if he's convicted.
At a news conference after the hearing, attorney Yale Galanter said Simpson will plead not guilty to all the charges at an arraignment scheduled for the week of October 22.
He and four co-defendants are accused of entering a Las Vegas hotel room and pointing guns at two men -- Alfred Beardsley and Bruce Fromong -- as they took sports memorabilia, along with Fromong's cell phone and Beardsley's cap and sunglasses.
The items in the room where the alleged robbery took place included various baseballs, plaques, a historical photo featuring J. Edgar Hoover and a mobile phone, a police report said.
Prosecutors contend Simpson and his co-defendants -- Walter Alexander, Clarence Stewart, Michael McClinton and Charles Cashmore -- committed kidnapping because they intended to use a weapon to hold or detain the men. See who's whom in the Simpson case »
Cashmore, 40, turned himself in Wednesday, according to a source with knowledge of the investigation. He was one of the two men seen in a surveillance video released Tuesday by authorities.
Police are requesting the public's assistance in finding the other man in the video.
Beardsley, 46, considered a key witness, was also arrested Wednesday. He was booked into the Clark County jail on a fugitive warrant, booking records show.
Beardsley was convicted of stalking in 2003 in California and was sentenced to two years, according to the California Department of Corrections. It's unclear how much of that sentence he served, but he was still on parole at the time of the alleged Las Vegas robbery.
Before his arrest, Simpson said he was merely retrieving sports memorabilia that belonged to him and said no guns were used. Police, however, said Simpson orchestrated the incident and that the suspects had at least two guns, which authorities recovered during searches. E-mail to a friend
