The Sun Journal reported that the man’s arm was cut off near the shoulder Friday in an apparent workplace accident, possibly with a band saw.

The leader of public works in Lewiston says it “had to be divine intervention” that two workers sanding sidewalks nearby happened to be trained in the use of tourniquets.

It is unclear whether surgeons were able to reattach his arm but the man is expected to survive.
