FBI Special Agent Harry Trombitas (trahm-BY'-tuhs) says the woman wearing sunglasses handed the teller the note at a Columbus Chase bank branch Wednesday morning.
Trombitas says in a statement that the off-duty officer wasn't aware of what was going on, but when the woman noticed him, she grabbed the note and fled. He says she tried to swallow the note as she was nabbed, then coughed it up onto the sidewalk.
The officer arrested the 40-year-old Columbus woman, Lois Harvey.
Harvey remained jailed Thursday after a judge set bond at more than $250,000. Court records do not list her attorney.
