WICHITA, Kan. (AP) — Two Wichita financial institutions say a few hundred customers were at risk of having their bank account information compromised after devices called skimmers were placed on at least five ATMs on the Fourth of July.

Intrust Bank spokesman Tom Morrison told The Wichita Eagle fewer than 200 accounts were exposed to skimming devices placed over credit and debit card readers to illegally obtain information. Fidelity Bank spokeswoman Katie Grover says fewer than 100 accounts were exposed at her bank on the same day.

Morrison says it was no coincidence that the skimming devices were attached to the ATMs on July 4, when none of the banks were open.

Morrison and Grover say customers will not be held liable for fraudulent transactions.
