Nerves are getting frayed in the Saguenay region following a second school fire in as many days.

The latest fire broke out Monday at l'�cole La Carri�re in the Chicoutimi section of Saguenay.

Police believe someone broke a window and set a fire inside the school.

Firefighters quickly doused the flames and there was only minor damage.

Police believe there might be connection with an earlier fire that gutted Le Roseau Elementary, also in Chicoutimi.

About 300 students were left without a school after the building went up in flames on Sunday.

Firefighters from Chicoutimi and two neighbouring municipalities worked for about six hours to douse the flames.

No one was injured but the school has been severely damaged.

Students will be transferred to other schools until repairs are complete.
