A Goldman Sachs banker has been charged with raping a young woman in an East Hampton rental home, the authorities announced on Thursday.

The banker, Jason Lee, 37, was arraigned on rape charges in court in East Hampton on Wednesday and posted $20,000 bail, according to a court official and a statement issued by the East Hampton Town Police Department.

Court documents in the case were not immediately available.

Mr. Lee is a managing director in Goldman Sachs’s equity capital markets group, which handles initial public offerings. He is on leave following his arrest, an official at the bank said.

Details of the case remain scarce. Police officers responded on Tuesday to a report of a disturbance at the four-bedroom home Mr. Lee and his wife had rented this summer just north of the Montauk Highway.
