Montreal police ask for help in daycare firebomb investigation

Police in Montreal are asking for the public's help in identifying three suspects wanted in connection with a series of daycare fire bombings.

The men were seen near the scene of the Bébé Einstein Daycare on Boulevard de la Rivière-des-Prairiesaround the time Molotov cocktails were launched at the building.

The first arson attempt took place on Sept.3.

The building suffered some damage in that attack and was closed pending repairs.

On Sept. 13, the day it was set to re-open, someone again tried to set the building on fire with an incendiary device. A third attempt was made later that day.

Descriptions of the suspects are available on the Montreal Police website.

One or more of the men may have suffered arm or leg burns during one of the arson attempts, police said.

Investigators have not said why the daycare has been repeatedly targeted.
