A Huntsville police officer was charged with driving under the influence of alcohol while he was off duty early Sunday morning, authorities said.

Justin Jamar Willis was booked into the Madison County jail on a misdemeanor DUI charge just before 5 a.m., records show. Willis was released about 12 hours later on $1,000 bail.

Attempts to reach Willis for comment weren’t immediately successful on Monday.

State troopers arrested Willis during a traffic stop near the intersection of U.S. 72 and Moores Mill Road, said Huntsville police Lt. Michael Johnson. A state trooper spokesman didn’t immediately return a call for comment.

Johnson said Willis will be on desk duty until the matter is investigated internally and the criminal case is adjudicated.

Willis, who turns 31 years old today, has worked at HPD for less than two years, Johnson said.

Further details weren’t immediately available.
