The U.S. government and the company formerly known as Cendant Corp. are suing the conglomerate’s imprisoned former chairman, seeking at least $22 million in assets they say he tried to hide.

The suit, filed in U.S. District Court in Hartford on Thursday, alleges Walter Forbes fraudulently transferred cash, securities and real estate to his wife and others to avoid creditors and a $3.2 billion restitution order.
