SPRINGFIELD, La. (AP) — A Livingston Parish grand jury has indicted the mayor and police chief of a Baton Rouge suburb on charges they conspired to hide a woman's 2011 drunken driving citation.

Louisiana Attorney General James "Buddy" Caldwell's office says Thursday's four-count indictment charges Mayor Charles Martin and Police Chief James Jones with obstruction of justice, criminal conspiracy to obstruct justice, injuring public records and criminal conspiracy to injure public records.

Martin and Jones were booked on related charges last year.

Caldwell's office says the 62-year-old mayor and 48-year-old police chief plotted to conceal evidence and obstruct the prosecution of a suspect arrested in April 2011 on suspicion of drunken driving.

Martin and Jones didn't immediately respond to a message left at the town's administrative office.
