Our witness tells us he grew upset, asking "So are you telling me I'm not going home today?"
As we previously reported, cops responded to a "disorderly person" -- AKA Riddle -- but when they met with him at the terminal, he apologized for his behavior. Cops did not file a police report ... and Riddle was free to go.
Of course, Riddle then went to Instagram to accuse an officer of sexual assault and harassment ... but the post was later deleted. The investigation into his claims remains ongoing.
Riddle -- who has faced multiple issues outside the ring during his career -- announced his departure from WWE on September 22.
