HOUSTON - A former KTSU Radio volunteer is behind bars on accusations he stole personal information from hundreds of donors.

Prosecutors believe Michale Whitfield, 32, stole credit card information from the pledge sheets of KTSU listeners and then used that information to buy electronics and gift cards.

Assistant Harris County District Attorney Donna Logan said Whitfield would sometimes buy products and resell them for cash.

Investigators said they have more than 20 confirmed cases.  They believe there could be up to 300 potential victims.

Whitfield faces enhanced charges because 14 of those cases involve senior citizens.  He is in Harris County Jail on $200,000 bond.

Texas Southern University issued this statement:

KTSU deeply regrets that it appears donors information may have been compromised. KTSU management takes this incident seriously and will be working with our own police department, legal counsel and other  law enforcement officials in every way to fully resolve this matter.

At the time of this alleged incident Mr. Michael Whitfield, was not, and is not an Employee of KTSU. He served as a volunteer for the radio station on an as needed basis.

We want donors to know that management has taken additional measures to ensure the security of donor information, including moving donor records to a more secure site to encrypt donor information. We are aggressively reviewing our  controls to ensure that this unfortunate incident  doesn't happen again.
