Citigroup Inc. did not intentionally turn a blind eye to Bernie Madoff’s massive Ponzi scheme, despite recognizing early warning signs through its dealings with a feeder fund, a Manhattan bankruptcy judge said Friday.

The ruling, from U.S. Bankruptcy Judge Stuart M. Bernstein of the Southern District of New York, came in a clawback suit from the trustee of Madoff’s estate to recover $343 million in transfers made to the the New York-based bank.
