The court-appointed trustee seeking to recover billions of dollars lost by jailed financier Bernard Madoff sued three entities Thursday to get back more than $30 million that he said the Madoff family had invested, mostly in oil and gas properties and technology companies.

The three lawsuits filed in U.S. Bankruptcy Court in Manhattan by Irving Picard are a follow-up to a lawsuit he filed in November seeking nearly $200 million from family members who he said lived lavishly while using the family finance business like a “piggy bank.”
