A former senior executive at committed suicide earlier this year after complaining that he was anxious about government investigations into the bank, a London coroner said Tuesday.

The executive, William Broeksmit, was found hanging in his London home in January. The 58-year-old Chicago native left a senior role at Deutsche Bank's investment bank in February 2013, but he remained an adviser until the end of last year. The London coroner, in an inquest on Tuesday, didn't give more details on what caused Mr. Broeksmit's anxiety.
