A woman was hospitalized after she was overcome by a toxic chemical when she and her children met her ex-husband for a custody visit Wednesday night at a Roseville park.
The ex-husband was arrested Thursday, Roseville police said in a news release.
First responders were called to Central Park at 2540 Lexington Av. at 7:40 p.m. Wednesday on a report of a woman suffering a medical emergency.
The woman was taken to a hospital, where tests determined that she had been exposed to a toxic chemical, police said. They did not identify the chemical.
“Out of an abundance of caution,” FBI hazardous materials experts and a support team from the Minnesota National Guard returned to the scene Thursday and determined that there was no threat to the public in the park.
