At least 3 arsons kept Portland Fire & Rescue crews busy through the early hours of Thursday, most in the same area where another arson was set one week ago.
The calls came in at 11:30 p.m. Wednesday and at 1:30 a.m., 2:35 a.m. and 3:45 a.m., PF&R officials said. None of them did a lot of damage and no one was injured, but the last one had a higher potential of greater harm.
That one brought crews to the US Bank Tower on SW 5th and Oak. One stairwell was smoke-filled and some combustible material was found on the 6th floor. Fires in high-rises are particularly tough to battle for obvious reasons.
