NASHUA — Flames broke out at popular downtown restaurant Chicken ‘n’ Chips shortly before the lunch hour

Monday, and firefighters answering the alarm arrived to find heavy smoke billowing from the single-story building at 12 West Hollis St.

There were no immediate reports of injuries to firefighters or civilians as of early Monday afternoon.

Crews were summoned around 11 a.m., and they began seeing smoke as they approached the scene.

Initial indications were that the fire may have started in the kitchen, and possibly involved a fryolator. Members of the city Fire Marshal’s office responded, and once the fire was declared under control, they began their investigation to determine the official cause and point of origin.

A follow-up story with additional details will be posted later at www.nashuatelegraph.com.
