JPMorgan Chase offered $1 million to settle sexual assault and harassment claims brought by a former investment banker weeks before he filed a lawsuit filled with lurid allegations that have captivated Wall Street, people familiar with the matter said. Chirayu Rana’s lawsuit in New York state court, which was refiled on Monday after being taken down for a week, alleged that a female colleague sexually assaulted him and that co-workers inside the nation’s biggest bank subjected him to racial discrimination. JPMorgan has said it conducted an internal investigation including multiple employees and doesn’t believe there is merit to his claims.
