A French court jailed Thursday two young men for four months for their part in a riot at a main subway station that ballooned into a major issue for France's presidential candidates. Prosecutors had called for six month sentences for the pair for throwing projectiles at police on Tuesday evening at the Gare du Nord during a riot sparked by the arrest of a fare-dodger. The court delayed proceedings against a third youth accused of having hidden a pair of shoes in a vandalised shop until April 25 following a demand from his lawyer. The 18-year-old will be detained until the hearing when video surveillance footage from the night of the riot should be available.
