Police and the FBI are looking for a woman who robbed two Northland banks and one Westerville bank last week.

The woman, dubbed the "church lady" because of her appearance, robbed Cooper State Bank, 1616 E. Dublin-Granville Road, around 9:30 a.m. Oct. 20; Key Bank, 1990 E. Dublin-Granville Road, around 10:30 a.m. Oct. 22; and BMI Federal Credit Union, 12 S. Cleveland Ave. in Westerville, around 4:45 p.m. Oct. 23.

In all of the robberies, the woman approached the bank tellers with a black day planner in hand, from which she drew a note demanding money and claiming that she had a gun, said FBI special agent Harry Trombitas.

In all of the robberies, the woman has worn a dark hat, long black coat and glasses. One of the hats was dark brown with an AC/DC logo.

Trombitas said police have received a number of calls offering tips about the woman's identity; however, he said none of those calls have yet led to an identification.

"We're working our way through the suspects," Trombitas said. "We don't have the person identified."

The woman is black, in her 30s or 40s and described as anywhere between 5-feet, 4-inches and 5-feet, 8-inches tall.

The same woman also is suspected of robbing Ohio Savings Bank, 2700 E. Dublin-Granville Road, on Jan. 10, 2006, Trombitas said, but she has not been connected with any robberies between that robbery and the three committed last week.

"I guess the question we have is: What happened between 2006 and last week?" Trombitas said.

He said the FBI is working with other law enforcement agencies to see if she could have been in jail, living somewhere else or connected to any robberies out of the area.

The woman's description and photo have been sent out to area banks, Trombitas said, and there is a reward for anyone who provides information leading to her arrest.

"We need to get her off the street as soon as possible, before anyone gets hurt," Trombitas said. "My hope is some one will see this woman enter a bank and recognize her and call police."

Anyone with information about the woman, or her potential identity, can call the Columbus Police Robbery Squad at (614) 645-4665, Westerville police at (614) 901-6866 or the FBI at (614) 744-2168.
