BOSTON (AP) - A class action lawsuit has been filed against Columbia Gas and its parent company on behalf of residents who were forced out of their homes for days when dozens of natural gas explosions and fires ripped through three Massachusetts towns.

Last week's explosions killed one person and injured more than two dozen in Lawrence, Andover and North Andover.

The lawsuit accuses the utility companies of negligence and seeks compensation for residents who had to evacuate but didn't sustain injuries or damage to their homes.

Frank Petosa, one of the attorneys who filed the lawsuit, said they are seeking to provide the families justice and hold Columbia Gas accountable.
