Laval police investigating possible dogfighting ring

Five pitbulls in Laval were euthanized after a citizen found them in a Chomedey parking lot, thin, malnourished and wounded.

Police believe they were used in dogfighting. Many had scars and wounds on their heads. Police said they had no choice but to euthanize them.

It happened in late January, but the police are going public now, asking for people's assistance. Anyone with information that might lead to an arrest should call the info line at 450-662-4636.
