Roaming Ontario and Quebec, the thieves have pried, drilled and torched open more than 130 cash machines since October 2010, making off with over C$700,000.

In November, the Halton Regional Police service decided to post its first video on YouTube, featuring CCTV footage of attacks, in a bid to generate leads.



With more than 60,000 views, the video has been "instrumental in generating leads which helped police to identify and arrest four people" in connection with the crimes this week.

Whether the medium - YouTube - or the message - a C$25,000 reward - was responsible for the positive response has not been specified.

The four gang members, Pierre Poirier, William Nolin, and Rejean and Maxime Lavigne have been hit with 65 charges with another 50 set to come from other jurisdictions.
