UPDATE: Channel 3 is learning more about an arrest involving a lieutenant with the Chattanooga Police Department.

Joseph Carpenter appeared in court for the first time on Monday, accused of driving under the influence while off duty.

The hearing was short, lasting for about a minute but Prosecutor Darren Gibson revealed there's more to the story.

"The BAC was significantly under the legal limit," Gibson told the judge.

Carpenter was pulled over earlier this month after a state trooper saw him driving without headlights on East Martin Luther King Boulevard.

The trooper wrote in a report, he saw Carpenter cross the yellow line and recorded him driving 67 in a 45 mile per hour zone.

Once stopped, Carpenter told the trooper he had two beers to drink.

A report states Carpenter failed a field sobriety test.

But during Monday's hearing, the prosecutor said a breathalyzer was also performed and Carpenter's blood alcohol level was significantly under the legal limit.

It's unclear exactly what his BAC level was or why that information was left out of the report.

Now, the prosecutor says he wants to learn more from the trooper who made the arrest.

"Nevertheless the state wants to be able to talk to the officer because there's a fairly decent speeding amount," Gibson added.

The judge agreed.

All sides will report back to court next month.

Carpenter has been placed on paid leave since the arrest.
