Fairfield Greenwich Group, the New York-based fund of hedge funds that was the biggest single investor with Ponzi schemer Bernard Madoff, has reopened its Manhattan offices.

The firm’s Third Avenue offices had been closed for several weeks, Clusterstock.com reports, leading to speculation that FFG was closing up shop.

The fund of funds, which lost more than $7 billion in the Madoff scandal, last month gave up control over four of its hedge funds, most of what was left of its business, and has been hit with a slew of lawsuits.

But the office has recent reopened, and Walter Noel, co-founder of Fairfield Greenwich and himself the target of many a lawsuit filed by investors burned by the Madoff scandal, has even been coming in to work, according to Clusterstock.com.
