Three people were arrested after a child was killed on Monday in Bois-des Filion, on the North Shore of Montreal.

David Provencher, spokesperson for the Terrebonne police, said that the Criminal Investigations Office is currently conducting investigations with the individuals and the crime scene is still under examination. He added that if charges are laid against any or all of them, they will appear before the Laval court on Tuesday afternoon. The case was transferred to the regional police.

Divers from the Sûreté du Québec (SQ) were deployed to conduct searches in the Mille-Îles River in an attempt to identify any potential evidence.

Provencher said, "We are trying to find anything that can be linked to this case."

This comes after a 911 call at 5:30 p.m. on Monday was transferred to the Terrebonne / Sainte-Anne-des-Plaines / Bois-des-Filion joint municipal police service about a "child seriously injured" in a house located on 34e Street.

The force indicated that "despite their efforts, the child was declared dead immediately."

The cause of death and the child's age were not disclosed, but the police acknowledged that they were "young."

The police did not mention the relationship between the three arrested individuals and the child, nor did they mention who was in the house at the time of death.

The grieving neighbors were dropping toys and teddy bears at a temporary memorial outside the house.

One of them told CTV News that he saw the child's mother sitting in the passenger seat of the family car on Monday night, crying uncontrollably.

Investigators and forensic technicians at both local and regional levels are still at the scene to analyze the circumstances that led to the child's death.

Anyone with information is encouraged to contact the police at 450-471-4121 or through Crime Stoppers at 1-800-711-1800.
