An officer started to feel sick while searching a car during a traffic stop, prompting Verona police to call the City of Madison Hazardous Incident Team on the night of July 31 night, but no foul substances were discovered.

The incident blocked off a lane of traffic on East Verona Avenue for more than an hour, drawing curious onlookers, who were told to keep a safe distance.

Lt. Mark Horstmann told the Verona Press it began with a traffic stop, which the police log classified as a drug investigation. He was on the scene the entire time, along with several other local first responders, as materials were tested and repeatedly came up negative for a wide variety of potentially dangerous substances.

After the hazmat team began packing up, police resumed the traffic stop, the result of which was not released as of 8 p.m. July 31.
