CHICAGO (CBS) — A woman was hospitalized in critical condition Wednesday night after a man poured nail polish remover on her during a fight in their Near North Side home.

The pair, both 59 years old, were involved in the fight shortly after 8 p.m. at their home in the first block of West Chicago, when the man poured “a quantity of a toxic chemical” on the woman, according to Chicago Police.

A police source said the man doused her in acetone, the active ingredient in nail polish remover.

The woman “inhaled the substance, resulting in severe respiratory distress,” police said. She was taken in critical condition to Northwestern Memorial Hospital.

The man has been located, police said. The nature of their relationship was not disclosed — police referred to him as an “acquaintance” — but the incident may have been domestic-related.

Area Central detectives were investigating.
