A Kansas prosecutor hasn’t decided whether to file criminal charges against a man who parked a pickup truck carrying homemade fireworks near the Statehouse.

Lee McGowan, chief of staff to Shawnee County District Attorney Chad Taylor, said Monday that the Capitol Police are still wrapping up their investigation of the Feb. 15 incident.

The Capitol Police initially described the devices found in the pickup as improvised explosive devices or homemade bombs, but later said they were illegal fireworks.

The truck’s owner parked the vehicle in a lot at the Kansas Judicial Center, across the street from the Capitol.

Officers detained the man in an underground tunnel connecting the Statehouse with an office building, but he was released.
