Lawyers say a court-appointed trustee wants the owners of the New York Mets to give up $300 million — money he says is fake profit from Bernard Madoff's epic Ponzi scheme.

The demand is made in a complaint ordered unsealed Friday in federal bankruptcy court in Manhattan.

The complaint by trustee Irving Picard names Fred Wilpon, Jeff Wilpon and others connected to the Mets and Sterling Equities as defendants. Lawyers agreed to make it public after settlement talks broke down.

The suit has cast a cloud over the Mets ownership, which has said it's exploring a partial sale of the team.

Madoff is serving a 150-year prison term.
