Greenwich (AP) - The Greenwich Police Department's first female captain has filed a state discrimination complaint against the town's top police officials.

Capt. Pamela Gustovich, a 27-year veteran of the department, was the first woman to rise to the rank of captain in Greenwich when she was promoted in 2012.

Greenwich Time reports that details of the allegations to the Connecticut Commission of Human Rights and the Equal Employment Opportunity Commission remain confidential.

Police officials say the accusations are baseless and that mediation has failed to resolve the dispute.

"The town has responded to the complaints, denying that there was any discrimination or other illegal action by the Police Department or the town," Police Chief James Heavey said.

Heavey would not provide details because it's a personnel matter.

Gustovich and her lawyer, Deborah McKenna of Stamford, declined to comment.

When she was promoted in 2012, Gustovich told Greenwich Time that her rise had less to do with her gender and more to do with "commitment and dedication." A 2011 graduate of the FBI National Academy program at Quantico, Va., she is vice president of the Connecticut Association of Women Police and former president of the Fairfield County Police Training Association.

In 2009, Greenwich settled a nearly four-year legal battle with eight minority police officers who complained of a hostile work environment and said they were held back from special assignments due to racial bias in the Police Department.

U.S. District Court in New Haven ruled in favor of five of the officers and ordered the town to pay them a total of more than $100,000.
