MINNEAPOLIS — Minneapolis police have arrested nearly two-dozen protesters during a rally outside a McDonald’s restaurant to push for a $15 an hour wage.

Police estimate around 130 people attended the early morning rally Tuesday in south Minneapolis. Police spokesman Scott Seroka says the predawn assembly was peaceful, but officers arrested 21 people. No one resisted arrest, and all were immediately released.

Fast-food employees, janitors and other low-paid workers attended the rally. Demonstrators chanted, waved signs and sat in the intersection as part of a “Day of Resistance for $15 and Union Rights.”

The Star Tribune reports some Metro Transit buses were briefly rerouted.

About 100 cleaners marched through an Eden Prairie mall to a Kohl’s department store Tuesday morning but were locked out. Another event was planned on the University of Minnesota campus.
