A Chicago alderman was thrown behind bars this week — charged with insurance fraud and obstruction of justice — for allegedly filing a false police report against a former fling, cops say.

Proco “Joe” Moreno, of the Windy City’s 1st Ward, was scheduled to appear in bond court Wednesday after being taken into custody the night before on an arrest warrant, according to local media outlets.

He is accused of lying to police back in January, when he reported his 2016 Audi A6 sedan stolen.

Moreno allegedly told cops that his ex-girlfriend, who has not been identified, was the only one who had access to the car. She was later pulled over and arrested for misdemeanor trespass to a motor vehicle.

Upon being questioned, the woman insisted that Moreno allowed her to use the Audi and that they had been dating on and off. Authorities investigated her claims and eventually dropped the charge against her.

Photos and text messages obtained by WGN showed Moreno telling the woman to pick up his car in early January — just one day before he reported it stolen, the outlet reports.

Moreno will be leaving office later this month after losing his bid for reelection. He is also facing a charge of disorderly conduct in addition to the obstruction of justice and insurance fraud charges.

The judge handling Moreno’s bond hearing, John Fitzgerald Lyke Jr., is the same judge who handled the proceedings for “Empire” actor Jussie Smollett — who was also accused of filing a false police report. Moreno’s bail was set at $100,000.
