FALL RIVER — Fall River police captain and former internal affairs head Gil Costa filed a lawsuit against the city and Police Chief Paul Gauvin under the state whistleblower's law for allegedly retaliating against him for internal affairs investigations he’d conducted for the department, claiming he was passed over for promotion multiple times since 2022 as a result.

Costa had demanded the city settle the matter for $150,000 or he would initiate the lawsuit.

“They have stalled Captain Costa’s career, damaged him financially, delayed his retirement, and forced him to work in unfavorable conditions,” wrote his attorney, Joseph Daigle in a July 9 demand letter submitted before the lawsuit filing. “He has been treated unfairly for merely doing his job and for reporting illegal activities.”
