Louisiana Woman, 38, Accused of Weeks-Long Sexual Relationship with Boy, 16, and Threatening Him to Keep Quiet: Police

A New Orleans-area woman was arrested earlier this week after she was accused of a weeks-long sexual relationship with a 16-year-old boy, authorities tell PEOPLE.

December Hebert, 38, was arrested Wednesday in Marrero, outside New Orleans, Jefferson Parish Sheriff's Office spokesman Col. John Fortunato says.

She was booked into jail Thursday and accused of carnal knowledge of a juvenile and indecent behavior of a juvenile, Fortunato says.

Hebert's bond was set at $5,000, according to NOLA.com, and she was barred by a judge from contacting the alleged victim. It was not immediately clear if she had entered a plea or retained an attorney.

Officials allege that Hebert convinced the victim to enter into a sexual relationship for about three weeks in April 2015, after the two first met through acquaintances, Fortunato says.

The Sheriff's Office was first contacted in May 2015 by a friend of Hebert's, after she learned of the alleged relationship, Fortunato says.

Hebert allegedly "threatened to harm" the boy in order to keep the relationship secret, Fortunato says.

Though a warrant was obtained for her arrest last year, following months of investigation, Fortunato says Hebert was "very transient" and hard to find.

She was only arrested on the charge after being investigated for an unrelated issue, he says.
