The Crown prosecutors office says three people and a train company will face criminal negligence charges stemming from a railway disaster that killed 47 people in Lac-Megantic, Que., last summer.
The prosecutor's office says 47 counts of criminal negligence have been filed against Thomas Harding, Jean Demaitre and Richard Labrie as well as the Montreal Maine and Atlantic Railway Ltd., the defunct railway at the heart of the disaster.
Rene Verret, a spokesman for the Crown's office, says the three men were placed under arrest late Monday afternoon.
Verret says the three men are employees of the railway company.
They will appear in court on Tuesday in Lac Megantic, Que., where they will face the charges.
The explosion was caused when a runaway train hauling tanker cars loaded with volatile crude oil broke loose and barrelled into the town in the early morning hours of July 6, killing 47 people and destroying part of the tiny Quebec community's downtown.
The Crown says in a statement that it elected to file the charges after an analysis of the evidence gathered at the scene.
