A prominent Deutsche Bank executive’s Manhattan death has been ruled a suicide, a spokeswoman for New York City’s Office of Chief Medical Examiner said late Friday.

The hanging death of Calogero Gambino, 41, a Deutsche lawyer and managing director, was discovered by his wife on Monday morning.

Gambino was found hanging by the neck from a stairway banister in their Manhattan home, according to police reports.

Gambino, an 11-year bank executive, was working with US regulators probing Deutsche’s involvement in Libor rigging scandal, the Wall Street Journal reported.

“Charlie was a beloved and respected colleague who we will miss,” said a spokeswoman for Deutsche. “Our thoughts and sympathy are with his friends and family.”

Deutsche and six other banks were fined by European regulators late last year for rigging the benchmark London interbank offered rate, Libor, used globally to set lending interest rates.

Deutsche, Germany’s largest lender, announced Friday it expects to record a $1.13 billion charge for litigation expenses in the third quarter. The bank’s legal costs totaled $3.8 billion last year.

Earlier this year, former Deutsche Bank Senior Managing Director William Broeksmit, who had close ties to co-CEO Anshu Jain, was found by his wife hanged in his South Kensington, London home.

Medical authorities in London ruled Broeksmit’s death was a suicide after a coroner’s inquest.

Broeksmit, 58, worked with senior executives in assessing the banks risks on its balance sheet.

The London coroner’s report in March cited Broeksmit as being anxious about the bank’s exposure as a result of Libor probes by European Union financial authorities prior to the suicide.
