Portland police declare riot Friday night after mayor's state-of-emergency extension

Police in Portland, Oregon, declared a riot in the northwest part of the city late Friday night after rioters began smashing windows, tagging graffiti on buildings and broke into a restaurant.

A resident who was filming the mayhem had a rock thrown through his window by a rioter, police said.

The unrest came after Portland Mayor Ted Wheeler extended the state of emergency in the city through the weekend over possible continued unrest, according to FOX 12 of Oregon.
