15 protesters arrested at city-wide rallies for Trayvon Martin

Fifteen demonstrators were arrested in Manhattan last night during protests over the acquittal of George Zimmerman, police said.

All of those charged were slapped with disorderly-conduct charges for obstructing traffic, cops added.

A Post reporter witnessed a few protesters throwing bottles at cops, but authorities said that no police or demonstrators were injured.

Marches and vigils in the five boroughs spilled over into the early morning hours and were largely peaceful, police said.
