Fire crews battle two-alarm fire on top of Portland's Yeon Building

PORTLAND, Ore. - It took more than 60 firefighters to put out a fire on the roof of the 15-story Yeon Building in downtown Portland late Wednesday.

Fire crews had to climb 15 stories with their gear to fight the fire. Nobody was hurt, but several buildings were evacuated.

Crews were working Thursday morning to determine what caused the two-alarm blaze. It took about 20 minutes to put it out.

Police found a 34-year-old woman who appeared to be suffering a mental-health crisis nearby. The woman was naked and climbing the flagpole on top of the Oregon Bank Building at 319 S.W. Washington St.

Police said the woman stripped, climbed the pole, removed the flag, then came back down and wrapped herself in it while holding a lighter and a fire extinguisher.

The woman was throwing construction glue from the roof, damaging cars below, police said.

Firefighters don't believe the woman was involved in the fire, however. Portland Fire & Rescue spokesman Damon Simmons said investigators questioned the woman and decided to pursue other leads.

Police took the woman into custody, and she was taken to a hospital for a mental evaluation.

The 103-year-old Yeon Building was Portland's first skyscraper.
