A female teacher in Fort Worth, Texas was jailed Wednesday after being accused of having a sexual relationship with a 15-year-old male student.

The teacher also allegedly traveled out of state with the boy without his parents' knowledge.

Alina Leung was a sixth and seventh-grade teacher at an all-boys school, where police said she met her teenage victim, according to the Fort Worth Star-Telegram, which first reported the story.

According to a online fundraiser for school supplies set up by Leung, she began teaching at the P.L. Dunbar Young Men's Leadership Academy in 2014.

The teen told investigators he had begun hanging out with Leung, 29, and other children in her classroom during his first year of high school.

In October last year, the two began emailing and chatting on Facebook, telling each other that they had feelings for one another, the boy said according to police.

'I mean it when I say I love you and want to be with you forever,' the teacher wrote in a message quoted by police.

'I hope you're not filling my head with fairy tales.'

According to police, another message sent to the boy by Leung read:

'I don't want anything bad to happen to either of us so we both need to watch out for the outside world. If you say we need to see each other less we will.'

Later, Leung and the boy began meeting up at her apartment while her boyfriend was at work. They used basketball games as an excuse for their secret appointments, the boy told police.

During their rendezvouses, the pair would watch movies but later began kissing and cuddling.

According to an arrest affidavit, Leung wrote in a Facebook message that she didn't want to have sex with the teen until he had reached legal age.

But police said the teacher had sex with the student for the first time shortly before Thanksgiving last year, and that the illegal intercourse continued in Leung's apartment and once in the backseat of her car.

The boy told police Leung took him on a trip to Oklahoma during the first week of Christmas break, where the two toured the Oklahoma University campus and stayed in a hotel.

The boy's parents were reportedly not aware their son had traveled out of state.

When police searched the boy's cell phone they found pictures of breasts, at least one of which showed Leung's face.

Leung was arrested at her North Richlands Hills apartment and charged with sexual assault of a child, unlawful restraint and improper relationship between a teacher and student.

The unlawful restraint charge stems from the teacher's alleged Oklahoma trip with the boy.

Her bail was recommended at $35,000.

Leung has been put on administrative leave from her job at the P.L. Dunbar Young Men's Leadership Academy, a spokesperson for the Fort Worth Independent School District told CBSDFW.
