(Watertown) No injuries were reported in an apartment fire in Watertown Thursday morning. Crews responded to the Riverview Apartments at 122 Hall Street just after 3:30am. The 32-unit complex was evacuated as personnel worked to locate the flames, which were found inside the walls of a vacant apartment on the first floor. The cause is being attributed to the replacement of plumbing in a nearby bathroom the previous day. The fire was contained, and no residents were displaced. Damage estimated at $5000.
