The Oak Ridge Police Department responded to the Y-12 Federal Credit Union on Tuesday morning, and the bank was cordoned off and then closed but it’s not clear why.
The ORPD has referred questions to the FBI office in Knoxville and the Knox County Sheriff’s Office.
The call to the ORPD came in at about 9:15 a.m. Tuesday. Officers blocked the entrance to the credit union, and at one point, they visually checked cars in a parking lot across Midland Road from the bank.
ORPD detectives were at the scene and remained there for at least a few hours afterward. The Credit Union is near the intersection of Lafayette Drive and South Illinois Avenue.
Credit Union employees appeared to be telling customers that they were closed for the time being. In a post on Twitter, Y-12 Federal Credit Union said its Oak Ridge Branch “is closed at this time. We apologize for the inconvenience.”
Oak Ridge Today has requested comment from the Knox County Sheriff’s Office, FBI, and Y-12 Federal Credit Union.
“Unfortunately, we cannot comment,” said Chris Smith, vice president of marketing at Y-12 Federal Credit Union.
He said there is an investigation, and the Oak Ridge branch will remain closed for the day. No other branches are affected, Smith said.
He said the FBI and ORPD could issue a joint statement later, possibly this afternoon.
Separately, several Knoxville media outlets have reported that about a dozen police and Knox County Sheriff’s Office cruisers had converged in the Whittington Creek subdivision off South Northshore Drive in Knoxville. But it’s not clear if the two events are related. Smith said he couldn’t comment on that.
The Knox County Sheriff’s Office referred all questions to the Knoxville office of the FBI.
More information will be added as it becomes available.
