Montreal police arrested three people on Wednesday in connection with a triple killing last August in the city’s east end.

Police issued a statement stating they arrested three men — aged 23, 25 and 26 — as part of their investigation into an Aug. 2 shooting that left three dead and two injured in the Riviere-des-Prairies—Pointe-aux-Trembles borough.

The older two men face three counts of first-degree murder, two counts of attempted murder and one count of possession of a firearm. The third man will be charged Thursday.

A 25-year-old woman was also arrested as part of Wednesday’s operation, but police said the arrest is unrelated to the killings and she will appear in court at a later date.

Police also executed four search warrants, seizing two handguns, ammunition, cellphones, narcotics and other evidence.

Since the killings, there have been a series of high-profile shootings in the greater Montreal area involving organized criminals and street gangs.

In response, the province has announced new police units to combat gun trafficking and gun violence.
