A reward is being offered for information on a fire at the old Ansonia Copper and Brass Building in Waterbury.
Fire broke out at the old factory at 725 Bank St. on July 30. The fire was so large it took firefighters hours to put it out and at one point the smoke plume was so large it appeared on Live First Alert Doppler Radar.
Waterbury Mayor Neil O'Leary said at the time that several other similar fires were the result of arson, and that he suspected that was the cause.
The Connecticut Arson Tip Award Program is offering a $2,500 reward for information that leads to an arrest or conviction in the case.
The building where the fire started was vacant for years. There were previous fires at the property, including a machine fire when the building housed a manufacturing company.
Anyone with information is urged to call the Connecticut Arson Hotline at 1-800-84ARSON or the Waterbury Police Detective Bureau at 203-574-6941.
