The Tennessee Bureau of Investigation have opened an investigation into embattled Rutherford County Sheriff Robert Arnold.
On Thursday, agents began looking into a report of a domestic complaint from Arnold's home this past holiday weekend, as well as questions about a possible cover-up.
Around 8:30 p.m. on Labor Day two squad cars with on-duty sheriff's deputies came to Sheriff Robert Arnold's Murfreesboro home.
The U.S. Attorney met with Arnold Tuesday in what was believed to be an inquiry into what happened over the holiday weekend.
An officials with the Rutherford County Sheriff's Office told NewsChannel 5 they did not find "any dispatch records, radio records, phone records or incident reports associated with any alleged event at Sheriff Robert Arnold’s home Monday."
Newschannel 5 was there when Arnold arrived to meet with officials at the federal courthouse in downtown Nashville. It was not clear if they were satisfied with Arnold's answers.
However, on Thursday the TBI issued this statement:
At the request of 16th District Attorney General Jennings Jones, TBI Special Agents are investigating the circumstances surrounding the report of and the response to a domestic complaint at the home of Rutherford County Sheriff Robert Arnold earlier this week.
Therefore it was still unclear what exactly made deputies respond to Arnold's home. The house is in the jurisdiction of the Murfeesboro Police Department, but no 911 call was made. The sheriff's deputies also did not file a report.
The D.A. who asked for the TBI's help -- expressed his concerns over Arnold's conduct earlier this year.
"If we don't have the trust of the public than we can't do our job. Law enforcement must be reproach," said General Jones in April.
Arnold was indicted on federal corruption charges with a trial set for early 2017.
He has been on pre-trial release since the indictment, but if the TBI finds Arnold was involved in a domestic incident he could lose that freedom.
Sheriff Arnold was indicted, but has been allowed to remain free living in his home, but depending on what the TBI finds he could end up jail until his trial in February.
Sheriff Arnold declined comment, and yes, it's true: Barring an ouster suit, Arnold would still remain sheriff even if he's incarcerated while awaiting trial.
