Halifax Regional Police say they have arrested a 40-year-old woman following a house fire in Dartmouth on Saturday.

The woman was apprehended at around 6:20 p.m., less than half an hour after firefighters responded to the fire on Pleasant Street.

The flames caused significant damage but were brought under control "quite quickly," said acting division commander Dennis Pitts with Halifax Regional Fire and Emergency. There were no injuries.

Firefighters deemed the blaze suspicious based on "observations found at the scene," police said in a release.

A police investigation is underway.
