You might hear them before you see them, as the Hells Angels roll into the city Friday night for their annual gathering and anniversary.

The group moved to Alberta 13 years ago and will hold a gathering at the local chapter’s clubhouse, just east of 84th Street S.E. near Chestermere.

Between 100 and 200 Hells Angels from more than fifty chapters of the organization typically attend this event.

Police confirm to 660News that there will be function on Saturday night.
