A sixth-grade teacher who is accused of having sex with a 13-year-old student feared retaliation from inmates within prison.

In exclusive bodycam footage, obtained by US broadcaster KPNX , Brittany Zamora, now 28, is seen talking to police during her arrest in Arizona last year.

The footage also shows her being taken to the police station where she is questioned over the allegations, but declines to talk about it without legal representation.

However, she did reveal how petrified she was of going to jail and her reasons why.

"I'm little, they're gonna tear me apart," she said during the interrogation.

In the bodycam footage, the parents of the teenager are also interviewed and reveal how their son "lost his innocence."

"His childhood is already gone," the father said. "He's 13."

Zamora's husband is also interviewed and reveals he supports his wife but refused to discuss the allegations against her.

"Brittany is an adult. She's the best, the best person I've ever known," he said.

The sixth-grade teacher at Las Brisas Academy Elementary School was arrested in March for alleged sexual misconduct with a student, police said.

The allegations were brought to the principal by the parents of the 13-year-old victim, who reported finding text messages between the teacher and the boy.

Police said the text messages indicated sexual activity both on and off campus.

Zamora is due back to face court again in May.
