What happened in Black Lake
Police located the vehicle after receiving information about individuals described as threatening. The available information does not indicate that anyone was injured during the intervention.
The SQ has not publicly identified the four people arrested, and no court outcome had been reported as of Friday morning. Arrests and police allegations are not findings of guilt.
The charge commonly described in Quebec as “possession of a weapon for a dangerous purpose” relates to the alleged way a weapon was possessed or used in circumstances considered dangerous. The specific evidence and any final charges must be determined through the legal process.
Sûreté du Québec investigation continues
Investigators were expected to continue gathering statements and establishing the circumstances that led to the arrests. That work may determine whether additional charges are laid, whether some people are released while the investigation continues, or whether any of those arrested appear in court.
Police have not released details about the type of weapon allegedly involved, whether it was recovered from the vehicle or whether the four people were known to one another.
The incident comes as the SQ continues several public-safety operations across Quebec, including recent road-safety enforcement and investigations into suspected drug trafficking and illegal cannabis activity.
