Florida teenager Kaitlyn Hunt, 19, has been jailed and charged over alleged sex with her 14-year-old girlfriend when she was 17.

HER family said she was arrested for being gay - sparking a huge wave of support from sympathetic Americans.

Now Florida teenager Kaitlyn Hunt, 19, has been jailed and charged over alleged sex with her 14-year-old girlfriend when she was 17.

Ms Hunt's family controversially claimed earlier this year that the victim's parents had gone to the police because of their daughter's gay relationship.

"They were out to destroy my daughter, they feel like my daughter 'made' their daughter gay," Kelley Hunt Smith, Kaitlyn's mother, said in a post on Facebook.

The one-time cheerleader had been offered a plea deal to keep her out of jail, The Daily Mail reports.

But that offer was revoked after revelations Ms Hunt had contacted the alleged victim almost daily since March 1.

That contact included 20,000 text messages, 25 pictures and secret meetings, according to prosecutors.

Ms Hunt's mother had tried to help her daughter cover her tracks.

'Delete EVERYTHING,' Smith wrote in a text message to the girl. 'PLEASE delete everything and make sure NO ONE finds out you've spoken to Kate at all.'

Court documents allege the two had sex as recently as July.

Ms Hunt was booked into the Indian River County Jail on Monday evening US time, WPTV reported.

She was previously charged and jailed in February but was released after posting a $5000 bond.

Ms Hunt is likely to face additional charges for breaking the terms of her bond at a hearing Tuesday.

Opinions about the case in her local community of Sebastian have become increasingly divided, the network said.

"It got too out of hand for it," a fellow student told the network. "That's why everyone kind of backed out of it. It just got way too out of hand than we thought it was going to be."

An online petition started by the family demands the prosecution be stopped has garnered more than 319,000 signatures since May.

The petition said: "(She is) facing serious felonies - all because she is in love" and many signatories believe it would not have occurred if she wasn't a lesbian".
