New York is about to have a new prosecutor overseeing its economic justice division. The job is going to Manisha Sheth, who is leaving Quinn Emanuel Urquhart & Sullivan after helping the firm wrestle $20 billion in settlements from banks that churned out mortgage-backed securities before the financial crisis.

Sheth, 42, joined Quinn Emanuel in 2008 after five years as a criminal federal prosecutor and four years as an associate at Davis, Polk & Wardwell. On Thursday she was named executive deputy attorney general for economic justice by state attorney general Eric Schneiderman.
