Rock Machine biker gang boss Jean-François Émard arrested in Valleyfield

Jean-François Émard, the presumed boss of the Rock Machine biker gang, was arrested by Quebec provincial police Sunday night.

A source within the Sûreté du Québec confirmed officers arrested the man in Valleyfield, about 45 minutes west of Montreal.

Last month, Émard publicly stated he was trying to revive the biker gang in Hawkesbury, Ont., just across the Quebec-Ontario border and not far from Valleyfield.

Since then, authorities in Hawkesbury have been actively working to dissuade the reformation of the gang on their territory.

The Rock Machine battled the Hells Angels in Montreal in a bloody turf war in the mid-1990s.

Émard is expected to appear in court on Monday in Valleyfield.
