A Hamlin Middle school teacher was arrested on charges of sexually assaulting a child and an improper relationship between an educator and student.

CCISD police reportedly issued a warrant for 47-year-old Anthony Quintanilla's arrest, but Nueces County jail officials told KRIS Communications Quintanilla surrendered Wednesday afternoon before a warrant could be served.

Quintanilla is the estranged husband of Texas A&M University-Corpus Christi President and CEO Dr. Kelly M. Quintanilla. The university released a statement Wednesday night from Kelly Quintanilla.

“I want to state that I had no knowledge of the allegations made against Mr. Quintanilla," it reads. "We lived apart for two years and are in the process of a divorce. If I had known or suspected any wrongdoing, I would have reported it to the authorities immediately. This is the only statement I will make regarding this situation and I ask for privacy for my daughter during this difficult time.”

Anthony Quintantilla is being held on a $300,000 bond.

Corpus Christi ISD Police Chief Kirby Warnke said he could not release any details on Quintanilla's arrest because the investigation into his case is ongoing.
