Pacman Jones Arrested ... Allegedly Spit On Jail Staffer (MUG SHOT)

7:10 AM PT -- The Bengals released a statement, saying "We are aware and working to gather full information, but policy is that it's inappropriate for the Club to comment on unresolved legal matters."

Another off-season ... another Pacman Jones run-in with police.

This time, the Cincinnati Bengals star was arrested Tuesday morning after allegedly getting violent at a Hyatt hotel ... and then spitting on a jail staffer.

Jones allegedly went ballistic at around midnight -- banging on a door and screaming and at one point, cops say he pushed and poked someone ... according to WLWT.

When cops arrived, he allegedly resisted arrest and then spit on a jail staffer while he was being booked.

The 33-year-old was eventually booked on misdemeanor assault, disorderly conduct and obstructing official business charges.

He's also facing felony harassment with a bodily substance for the alleged spit attack.

Jones just appeared in court, wearing a red vest and appearing frustrated. The judge set his bond at $37,500 and said he must stay away from the alleged victim.

Jones is no stranger to legal trouble ... back in 2015, he was kicked out of a casino for disorderly conduct.

In 2013, he struck a woman in a nightclub incident (he was found not guilty).

In 2011, he was arrested for disorderly conduct while intoxicated and resisting arrest.

He was also arrested in 2005 ... and 2006.
