A would-be bank robber came away empty-handed but left behind something useful for police: her photo identification.

The woman was arrested less than an hour later on a charge of attempted armed robbery, Police Commissioner William Dwyer said.

The woman filled out an account application Thursday morning, then pulled a handgun and demanded cash, Dwyer said. She panicked and fled without getting any money; police found an address on the account application, along with her photo ID.

The address was for an apartment near the bank. The manager gave the woman’s new address to police, who arrested her without incident.

“We’re probably not dealing with the smartest person in the world,” Dwyer told The Detroit News for a story published online Thursday.
