A 10-alarm fire that reduced a luxury apartment complex in Waltham to a smoldering pile of rubble last month and caused $110 million in damage was intentionally set, authorities said, and cash rewards are being offered in the hopes of catching whoever sparked the blaze.
The 264-unit building on the banks of the Charles River went up in flames during the early morning hours of July 23 and the roaring inferno damaged two other nearby structures and at least 20 vehicles, according to a joint press release issued by State Fire Marshal Peter J. Ostroskey, Waltham fire Chief Paul Ciccone and Waltham police Chief Keith MacPherson.
