A former state senator who quit the Legislature over a domestic violence incident involving his ex-girlfriend has sued the city of Phoenix.

Republican Scott Bundgaard alleges that city employees conspired to falsely portray him as an abuser rather than a victim in a February 2011 fight on a north Phoenix freeway.

The Arizona Republic reports that Bundgaard is seeking an unspecified amount in damages. He filed a $10 million notice of claim against Phoenix police and city officials in June. That's a precursor to a lawsuit.
