(CNN) New England Patriots owner Robert Kraft has been charged with soliciting prostitution at a Florida spa just hours before the Patriots played in the AFC Championship Game, according to a probable cause affidavit filed in Palm Beach County.

The 77-year-old billionaire is among 25 people charged with soliciting another to commit prostitution, State Attorney for Palm Beach County Dave Aronberg said Monday.

The charges resulted from a monthslong investigation into sex trafficking that focused on several central Florida day spas and massage parlors suspected of being used for prostitution. The investigation began when a health inspector observed curious details that suggested women might be living at the day spa.

Kraft faces two counts of soliciting someone to commit prostitution. He allegedly visited the Orchids of Asia Day Spa in Jupiter on January 19 in the afternoon and again on the morning of January 20, according to the affidavits.

The Patriots beat the Kansas City Chiefs in Kansas City later on the 20th to advance to the Super Bowl.
