Calogero Gambino, 41, was found on the morning of Oct. 20 at his home in the New York borough of Brooklyn and pronounced dead on the scene, according to New York City police.

Gambino was an associate general counsel and a managing director who worked for the German bank for 11 years, according to the Wall Street Journal, which first reported his death.

He had been closely involved in negotiating legal issues for Deutsche Bank such as a probe by regulators of banks over allegations they manipulated the Libor benchmark interest rate as well as currency markets.

Gambino was also an associate at a private law firm and a regulatory enforcement lawyer between 1997 and 1999, the Journal said, citing Gambino's LinkedIn profile and conference biographies.

He died by hanging, said Julie Bolcer, spokeswoman for the New York City Office of Chief Medical Examiner. The manner of death was suicide.

"Charlie was a beloved and respected colleague who we will miss," said Deutsche Bank in a statement. "Our thoughts and sympathy are with his friends and family."

Deutsche, Germany's biggest lender, has already paid 6 billion euros ($7.7 billion) in fines and settlements in the past two and a half years. It expects to post litigation costs of 894 million euros alone for the third quarter of 2014.

Earlier this year, former Deutsche Bank manager William Broeksmit, who had close ties to co-chief executive Anshu Jain, had been found dead at his London home in what also appeared to have been a suicide.
