The owner of a home in Fairfield where police found an arsenal of explosives and weapons was arrested on Monday and a private contractor is removing chemicals from his home.
Officers went to the home of Joseph Callahan on Oct. 1 after someone from out of state asked police to check on Callahan. They returned after Callahan called police himself to report a burglary at his house.
When police arrived, they said Callahan seemed "out of sorts" and saw a "significant" amount of chemicals, according to authorities.
Inside the house, police found hundreds of firearms, thousands of rounds of ammunition, chemicals and explosives. Officers also discovered 250 gallons of jet fuel, according to police.
Callahan, 69, was taken to the hospital for an evaluation.
On Monday, police charged Callahan with illegal possession of explosives, manufacturing bombs and reckless endangerment. He was released on a conditional promise to appear in court.
Callahan is cooperating with the investigation and has agreed to do whatever is necessary to help remove any hazardous materials from his home, police said.
State and local fire marshals are supervising the chemical removal, along with the Fairfield Police and Fire departments.
He is expected to be in court on Oct. 16.
