A Pennsylvania Department of Revenue supervisor has been charged with setting up a staffer to unknowingly rob a bank as a joke.

Gladys Smith claimed she was playing trick on Sharon Mingle, an employee, when she gave her a note to turn in to a PSECU credit union teller last Friday morning, according to PennLive.

But Mingle, didn't read the paper that said "put the money in the bag," and unwittingly gave the note to the teller at the Strawberry Square branch in downtown Harrisburg.

Within three minutes, about 10 Capitol police officers swarmed the scene with lights and sirens blaring, after the teller punched the panic alarm, the story said.

A surprised Mingle was arrested and told police she simply followed Smith's orders. When questioned by police, Smith admitted she set up Mingle.

Smith "admitted she gave her the note as a joke," Troy Thompson, press secretary for the Pennsylvania Department of General Services, told the website. "She told her to take it down to the credit union, and basically bring back what they gave her."

Smith was charged with disorderly conduct. Mingle wasn't charged.

A Department of Revenue spokesperson could not be reached for comment, and neither could Mingle nor Smith, PennLive said.
