A teenage girl who was drugged and raped by sex traffickers over a three month period has been rescued by a hero postman who heard her cries for help.

Crystal Allen, 16, says she was repeatedly raped, drugged, beaten and tied to a chair at a property with guard dogs in California.

"They made it impossible [to escape]. They had guard dogs and people that would watch us all the time and not let us leave. I was tied to chairs," Allen told KCRA TV.

Allen feared she wouldn't ever get to see her family again.

That's until a tiny window of opportunity became available after her screams for help were heard by a local postman.

On June 8 Allen was being driven around by her captor when she suddenly grabbed a phone in the car, leaped out and starting running and screaming for help.

Postman Ivan Crisostomo was making a delivery when he heard Allen's distressed cry.

"I hear this crying, this desperate crying. I saw her hiding behind this kind of bush, kind of tree," Crisostomo told Fox 40.

"She started to point to her arm, saying, 'They were putting things in me. They were putting things in me. They are coming to get me'."

The postie then hid Allen in his truck and protected her until police and ambulance crew arrived.

"Don't worry," Crisostomo told Allen. "Nobody's going to take you. I'm here for you. Don't worry."

After being taken to hospital, Allen is now home with her family.

According to media reports, Allen had been lured in by a "friend" who turned her over to a sex trafficker.

Allen and Crisostomo have since reunited following the ordeal, with the teen thanking the postie for rescuing her, potentially saving her life.

"Ivan himself is a hero for saving me," she told Fox 40. "Even though he doesn't think it."

However, Crisostomo believes it's just part of the job.

"We, as mailmen, we have a duty, as human beings, being there, knowing the people," he said.

"We have a kinda different responsibility a little bit with our neighbours and with the people we serve. That's how I see it."
