(CNN) — Most of the commercial-grade fireworks stolen from a CSX train in the Midwest this week have been recovered, federal officials said Saturday.
Agents from the Bureau of Alcohol, Tobacco, Firearms and Explosives said a tip led them to recover 30 out of the 32 cases taken from the train Wednesday.
Authorities have made no arrests and the investigation is ongoing.
The train departed was headed to Detroit from Chicago, and it’s believed the cases were stolen while the train was stopped in Ohio, ATF spokeswoman Ginger Colbrun said Friday.
The theft was discovered when the train arrived in Detroit, CSX spokesman Rob Doolittle said.
While the motive is unclear, Colbrun says it could range from profit to entertainment, based on previous commercial fireworks trafficking cases.
“It is an unusually large amount of fireworks to be stolen,” Colbrun said.
The fireworks in question are considered very dangerous and not meant for public use. The cases contained 2½-inch to 5-inch aerial fireworks.
CSX is working with the ATF to recover the remaining two cases. Anyone with information on the theft is asked to call 313-202-3400.
