Thomas Infante walked into a Chicago bank around 5:50 p.m. last Friday and handed a teller a note that read “Be Quick Be Quit. Give your cash or I’ll shoot,” according to an FBI affidavit filed today. The teller gave the man about $400.

Then, typical of a stupid criminal act, Mr. Infante left behind his demand note, written on a torn half of the pay stub. Investigators found the other half of the note – with Infante’s name and home address – outside the bank’s front doors. The pay stub showed Infante was paid $165.99 by Jewel Food Stores on Oct. 23, according to the FBI.

“It’s fairly unusual that we see something that specifically stupid,” said FBI spokesman Ross Rice. “But overall, we see a lot of strange bank robberies.”

Infante was arrested at his Cary home and later confessed to the robbery, according to the FBI affidavit.
