A former in-house attorney at Goldman Sachs & Co. has alleged she was fired from the bank after trying to give internal investigators information on an inappropriate relationship between the legal department’s head of litigation and a younger female attorney.

Marla Crawford filed a lawsuit Monday in the New York State Supreme Court for New York County bringing claims of discrimination and retaliation against Goldman Sachs, head of litigation Darrell Cafasso and general counsel Karen Seymour.
