12:59 PM PT -- Pacman's lawyer Tim Schneider tells TMZ Sports he believes the NFL star was thrown out of the casino under suspicious circumstances.
Schneider says Pacman had been gambling loudly with friends for several hours -- and losing -- and the casino had no issue.
It was only when Pacman's luck began to change that his volume became a problem.
Schneider says when Pacman was asked to leave, he did so without incident and says, "No charges came about as a result of the incident."
Pacman Jones was kicked out of a Cincinnati casino for berating staffers and patrons in the hours before he was arrested at a Hyatt hotel on January 3 ... TMZ Sports has learned.
Cincinnati PD has confirmed Jones was "acting disorderly" at JACK Cincinnati Casino and was asked to leave. Security and police escorted the NFL star out of the building.
One witness tells us Jones had verbally attacked employees at the casino and had an altercation with a casino patron who was trying to record the incident on his cell phone.
We're told Jones also went off on a police officer who responded to the scene and was "fired up" as he left the premises.
Of course, Jones later went to a nearby hotel where he was arrested for allegedly getting physical with a hotel security guard.
When cops arrived at the hotel, Jones continued his aggressive behavior and told the arresting officer "suck my d***" and "I hope you die."
Jones issued a statement saying he was embarrassed by the arrest video and is taking anger management courses.
We reached out to Jones' rep for comment about the casino incident -- so far, no word back.
It's not the first time Jones has been booted from a casino -- he was kicked out of the Hollywood Casino in Indiana in 2015 after going off on casino staffers.
