NEW BEDFORD - New Bedford Police and Fire personnel are investigating a fire at a north end construction site.

The fire was reported at 6:40 a.m. Tuesday at 78 Rosa Drive near the Pine Grove Cemetery.

Upon arrival, firefighters found a small exterior fire on the unfinished home at the site. The fire was quickly extinguished.

New Bedford Fire Chief Michael Gomes tells WBSM News the cause of the fire is under investigation, but says it does not appear to be connected to a string of arson fires throughout the city this summer.
