Police obtained a search warrant to investigate what they said Wednesday might be explosives, based on firefighters' reports after they responded to a call to the apartment because of a smoke and a fire in the apartment's kitchen, the Hartford Courant reported.
Firefighters inspected the first-floor apartment and discovered what they thought may have been bomb-making materials, police said. Police said they discovered a small amount of large M80 and M100-type fireworks in the residence.
Christopher Clark, 26, the occupant of the first-floor apartment where the fireworks were discovered, was being questioned by police. Clark hasn't been charged with anything.
The FBI, the New Haven Police Hazardous Device Unit and detectives responded to the incident, the newspaper said.
