NewsCenter 16 is learning more about the source of a bank breach that's caused headaches for dozens of people in Michiana. As we've been reporting, many people have seen fraudulent withdrawals from their bank accounts.

On Wednesday, 1st Source Bank officials say these recent problems are related to a breach they had on May 12th. 1st Source Bank’s Jim Seitz tells Newscenter 16 that the problem can be traced back to last month, when hackers hacked into a server and stole their customers' information. Just this week, Seitz says 1st Source learned that the hackers also got away with non-1st Source customers’ numbers-- if those people used one of their ATM machines.

Local police continue to take dozens of reports on this recent string of bank fraud. As of Wednesday afternoon, here's a look at the number of some of the confirmed bank fraud reports in our area. St. Joseph County Police have taken 45 bank fraud reports. South Bend Police have taken 26 reports and Mishawaka Police have taken 14. (Note: these are just the confirmed reports to date.)

Victims, like Hollyann Tuholski, have been on the phone with their banks over the last couple days. 1st Source officials tell us the other banks involved have been alerted. “We met this morning with a group of fellow bankers and it appears all of the banks who were at the meeting had received lists and are taking appropriate action to protect customers,” says 1st Source’s Jim Seitz.

“I don't feel bad about doing any of this, creates a lot of work, but I'm willing to do it as long as we can figure out where breach happened and prevent it from happening again,” says Hollyann Tuholski, a bank fraud victim.

If you have a fraud issue, police are encouraging people to not only contact their banks, but file a police report as well.

To prevent future identity theft and fraud, 1st Source Bank customers were issued new cards this month. Meantime, bank officials say the hackers/thieves didn't get any personal information from the non-1st Source Bank customers who were exposed in this incident.
