The release stated that in addition to the criminal investigation, the Sheriff’s Office has launched an Internal Affairs investigation into the incident. 

"We take allegations of domestic violence especially seriously, particularly when they are made against those who are sworn to protect our community," Harris County Sheriff Ed Gonzalez said. "The allegations made in this case are very disturbing, and will be thoroughly investigated."
