Los Angeles, California (CNN) -- The judge overseeing the Mel Gibson child custody case ordered a probe into the leak of sealed court documents published on celebrity news website TMZ, a lawyer in the case said. The confidential documents "were stolen probably from the court" and the leaker "got paid a good deal of money," said Martin Garbus, an attorney for Gibson's ex-girlfriend, Oksana Grigorieva. Grigorieva and Garbus discussed the leaks in an interview scheduled to air Wednesday night on CNN's "Larry King Live." "It's medical documents, declarations, court opinions, transcripts, everything it seems," Garbus told King. TMZ has published sworn statements from Gibson, Grigorieva and another witness in the court fight over custody of 1-year-old Lucia.
