The owner of a Post Road East auto parts shop faces criminal charges after police said they found a large amount of illegal fireworks on his business' premises.

The cache of explosive materials, police said, "posed a serious incendiary danger to persons and property."

Sanford Cooper, 64, of Easton, turned himself in Sunday after learning that a warrant had been issued for his arrest.

The charges were lodged after Westport police joined State Police in May to search Cooper Auto Parts, 1763 Post Road East, where they said they found a large amount of fireworks stored in a rear storeroom.

State Police personnel examined the fireworks and determined that they exceeded the amount an individual is legally allowed to possess in the state, according to the report.

Cooper's Easton home was destroyed by an inferno earlier last May, a fire that authorities also charged was fueled by fireworks. Cooper faces charges in connection with that incident as well.

Westport police charged Cooper with sale, use and possession of fireworks, illegal possession of explosives and the storage/transportation/use of explosives and blasting agents.

He posted a $5,000 bond and is scheduled to appear Oct. 31 in Norwalk Superior Court.
