Credit Suisse has launched an internal investigation into allegations that a managing director harassed interns at a work party hosted by the Swiss bank, finews.com has learned.

The rumor spread life wildfire from Credit Suisse's Madison Avenue U.S. headquarters in New York, according to U.S. investment banking portal «Dealbreaker»: a managing director in mergers and acquisitions reportedly harassed summer interns at an outing sponsored by the Swiss bank, locking himself in an room with one until other interns called security.

«Dealbreaker» cited anonymous tipsters in its reporting. The bank responded to finews.com that «We launch full, confidential investigations into any matters that concern alleged inappropriate behavior». «When a full investigation is complete, decisions about any disciplinary actions are taken at that time», a spokesman said.

Thiam's Zero Tolerance

The bank hit back at the report's suggestion that staff had been told to keep schtum about whatever – if anything – happened at the company event. «Employees are actively encouraged to come forward with any information they have about incidents like these», the spokesman said.

CEO Tidjane Thiam recently pledged zero tolerance against harassment, getting personally involved in an eight-year-old case at the bank after a former employee personally appealed to him in writing.
