MONTREAL - Montreal police believe attacks against five Jewish institutions in the city on the weekend could be related.

Const. Raphael Bergeron says three synagogues, and a Jewish school and daycare located in the west-end areas of Cote St. Luc and Hampstead Montreal-West, had windows broken.

He says the attacks took place sometime between Saturday afternoon and Sunday morning.

No arrests have been made.

Bergeron says police believe the same suspect or suspects were behind all the attacks.

Police have no eyewitnesses but say they will examine surveillance video from one of the premises or from nearby businesses.
