A trustee trying to recover money for victims of disgraced financier Bernard Madoff is demanding $300 million from the partnership that owns the Mets, which he says were fake profits from the massive fraud, according to a lawsuit unsealed Friday.

The suit in federal bankruptcy court in Manhattan names Sterling Equities, along with its partners and family members, including Met owner Fred Wilpon, team president Saul Katz and chief operating Jeff Wilpon, the owner’s son.
