Ald. Ricardo Muñoz has led the 22nd Ward for 25 years.

Ald. Ricardo Muñoz (22) was arrested Wednesday in connection with a domestic violence incident that took place on New Year’s Eve, Chicago police said.

Muñoz was taken into custody at his aldermanic office without incident, Chicago police spokesman Anthony Guglielmi said.

The victim told police “that a verbal argument took place between [the alderman] and his wife where the offender pushed and struck the victim throughout the body.”

The investigation is ongoing, Guglielmi said.

Muñoz, who was still in custody Wednesday afternoon, did not respond to a text message from The Daily Line. The alderman has not been charged.

Muñoz’ wife, Betty Torres-Muñoz, filed Wednesday for an order of protection in Cook County Domestic Violence Court, according to the Tribune.

Muñoz announced in July that he would not run for another term representing the 22nd Ward, which includes North Lawndale, Little Village, Brighton Park, LeClaire Courts, Archer Heights and Sleepy Hollow.

Muñoz, 53, first appointed to the City Council by Mayor Richard M. Daley in 1993, belongs to the council’s Latino and Progressive caucuses, and has been long a thorn in the side of Mayor Rahm Emanuel.

Joanna Klonsky, a spokeswoman for Muñoz, declined to comment on the alderman’s arrest.

Muñoz has been open about his struggles with alcohol. When he told NBC5’s Carol Marin the news of his retirement, he said he revealed his alcoholism eight years ago in an effort to take “alcoholism and mental health out of the shadow.”

In addition, Muñoz was arrested as a teenager on drug and gun charges, which were later expunged.

Muñoz has endorsed 22nd Ward committeeman Mike Rodriguez, the executive vice president of the Cook County Democratic Party, to replace him as alderman.

“I am deeply troubled by the reports surrounding Ald. Muñoz’s arrest,” Rodriguez said. “Domestic violence is never acceptable in any form, and these allegations should be taken extremely seriously.”

Also running to replace Muñoz are Lisette Lopez, Richard Juarez and Neftalie Gonzalez.
