(CNN) When the white Bentley of New England Patriots owner Robert Kraft was pulled over after cops say it left a day spa, the billionaire asked an officer whether he cheered for the Dolphins and showed him one of his Super Bowl rings, according to a motion filed by prosecutors this week.

The stop took place on January 19 as Kraft's driver pulled away from the spa in Jupiter, Florida, where authorities say scores of men were getting illegal sexual favors, the document says.

Kraft was a passenger in the car and was very polite and respectful to officers, Palm Beach County prosecutors said in their motion, citing police body camera footage.

He asked whether an officer was a Dolphins fan, told the officer that he was the owner of the Patriots and said that his driver was "being nice by taking him somewhere."
