Chad Johnson was just arrested in Florida -- after a smoking hot Broward County judge determined the ex-NFL star violated his probation stemming from his 2012 domestic violence bust ... TMZ has learned.
We broke the story ... a warrant had been issued for Johnson's arrest earlier this month after he failed to report to his probation officer on 2 occasions AND failed to show proof of enrollment in a domestic violence education class.
Johnson's probation stemmed from his domestic violence conviction involving ex-wife Evelyn Lozada last year.
35-year-old Johnson appeared in a Broward County courtroom over his alleged probation violation -- and moments ago, the judge determined Chad WAS in violation and ordered him to be arrested and jailed.
Chad tried to tell the judge how the entire situation was a big misunderstanding -- but she wasn't having it ... watch the video.
TMZ has obtained Johnson's booking sheet -- he's listed as 6'4" 190 pounds.
Bond has been set at $1,000.
