PORTLAND, Ore. (KOIN) — The City Target in downtown Portland filled with smoke early Friday evening after someone lit toilet paper on fire inside the store.

A number of Portland Fire & Rescue units responded to the store at SW 10th and Morrison. Officials told KOIN 6 News the real challenge was clearing the smoke because of the size of the building and poor ventilation.

There were no reported injuries. No further information is available at this time.
