NORWALK - Fire officials say fireplace ashes are to blame for a blaze in Norwalk.

It happened yesterday on Thorn Apple Way.

Firefighters say the homeowner dumped the ashes next to the house yesterday morning. Several hours later, flames spread up the side of the home damaging the rear siding and part of the roof.

Norwalk fire officials are asking all city residents this weekend to install working smoke detectors throughout their homes.
