A retired police detective has filed suit against the city of Cranston in federal court, alleging that he was discriminated against based on his disability and was forced to retire.

Ronald Jacob claims in the lawsuit that city officials violated the police labor contract, the Rhode Island Civil Rights Act of 1990 and the U.S. and Rhode Island constitutions.

Jacob says he suffers from coronary artery disease as well as extreme anxiety and depression. He's alleged that the misrepresentation of physicians' findings regarding his disability prompted his March 2005 retirement and cost him financially.

Jacob retired with a service pension and not the more lucrative disability pension. He's seeking compensatory and punitive damages.

City attorney Tim Bliss says Jacob never applied for a disability pension.
