LUBBOCK, Texas (AP) - A vice president at Lubbock's University Medical Center has resigned after a routine internal audit turned up possible employee embezzlement.

The hospital said Tuesday Greg Bruce, its vice president of corporate services, quit. Spokesman Eric Finley told the Lubbock Avalanche-Journal he wouldn't comment on the amount of money embezzled, whether Bruce was involved or when the loss was discovered.

Bruce wouldn't elaborate on a statement released by the hospital. He supervised several administrative departments at the hospital for the past six years. The Lubbock County Commission appoints the hospital's board of managers.

The hospital says it's cooperating with an ongoing investigation by the FBI and federal prosecutors. It treats some 300,000 patients annually from West Texas and Eastern New Mexico.
