Multiple employees from the Travis County Tax Office were arrested Friday on suspicion of fraudulent activities.

According to a statement from Travis County Tax Assessor Collector Bruce Elfant, investigators from the Texas Department of Public Safety arrived Friday afternoon at both the main office and satellite office to serve search warrants and arrest employees.

The investigation began as a result of an internal audit conducted by the Travis County Auditor, Elfant said.

"Since this is an ongoing investigation, I am not able to discuss any further details. However, please know I am appalled and extremely disappointed that members of my staff have been implicated in fraudulent activities that have violated the trust of Travis County residents," Elfant said.

Travis County Judge Sarah Eckhardt said in a statement she was "deeply troubled" when informed of the arrests and spoke with Elfant as the arrests occurred.

"Travis County is in full cooperation with the Texas Department of Public Safety and the Texas Department of Motor Vehicles to address the issue and restore the public trust," Eckhardt said.

According to Elfant, all satellite county tax offices are closed until further notice. However, the main tax office will remain open.
