MINNEAPOLIS (AP) - 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."

Some Metro Transit buses were briefly rerouted.

Protesters and their supporters were heading to a Kohl's department store in Eden Prairie. Another event was planned late Tuesday afternoon on the University of Minnesota campus.
