New Lac-Mégantic disaster charges laid

New additional charges have been laid in the Lac-Mégantic, Que., train derailment and explosion.

The Canadian government issued a notice on Monday saying charges would be laid under the Railway Safety Act and the Fisheries Act.

"Transport Canada's investigation under the Railway Safety Act found that an insufficient number of hand brakes were applied to the train and that the hand brakes were not tested properly," the government said in a release.

The release also cited Environment Canada's investigation into the depositing of a "deleterious substance into fish-bearing waters with the release of crude oil into the immediate environment of Lac-Mégantic and the Chaudière River."

It is unclear who is being charged and what the exact charges are, but CBC News has learned that people in Canada and the United States are being served.
