A bank robber solved his own crime for authorities last week, leaving a pay stub with his name and address at the scene, according to the Chicago office of the FBI.

Thomas Infante, 40, was arrested after the Fifth Third Bank at 4017 West Lawrence was robbed on Friday.

Infante walked into the bank and handed a teller a threatening note demanding cash, according to an FBI news release. What the FBI said they noticed but Infante failed to consider was that the note was written on the back of his own pay stub.

When he fled the bank, Infante left the note behind, including a torn-off portion dropped outside the bank that included his name and address, the FBI said.

Infante was arrested at his home in Cary, Ill., where he allegedly confessed to the robbery.

And the take wasn’t even that good — the teller only handed over $397, according to a criminal complaint.

If convicted, he could spend up to 20 years behind bars.
