Bella Culley went missing in Thailand. Her family found her, pregnant and in jail.

In April, 19-year-old Bella May Culley embarked on a gap year, travelling around Southeast Asia before she started her career as an aspiring nurse.

She left her hometown of Billingham in the UK to travel to the Philippines, according to The Independent, before moving on to explore Thailand in early May.

Within days, the holiday would take a dark turn.

Soon after arriving in Thailand, Bella was reported missing. Suddenly, the teen, who had remained in close contact with her family during her trip, was radio silent.

Then, on May 10, Bella resurfaced at Tbilisi International Airport in Georgia, carrying a large amount of cannabis.

Bella claimed she was tortured by a Thai gang and coerced into smuggling drugs. The Georgian justice system wasn't so sure.

This week, after six months behind bars, Bella was released from prison.

This is her story.

What happened to Bella Culley?

When Bella disappeared, her family said they "feared the worst".

"Nobody knew where she was," her grandfather William Cutley told The Mirror earlier.

Then the call came that she was in jail. William couldn't believe it.

"She was on holiday with some friends, doing what 18-year-olds do — drinking and dancing," he said.

Suddenly, Bella was facing up to 20 years in jail or life imprisonment if convicted.

At 80 years old, he worried he might never see his granddaughter again.

"She's got sucked into something, somehow. She's not an international drug trafficker," he said.

"She's not daft, she's an intelligent girl. Why has she done it? Has someone dangled money in front of her? We just don't know what has gone on until we get out there and talk to her. We are just hoping that somebody can do something. She must be terrified."

During a pre-trial hearing, Bella told the court she became involved with a Thai drug gang, who coerced her with the threat of violence to herself and her family to transport drugs into Georgia.

The teenager said she had been "forced to do this through torture".

"I just wanted to travel," she said, per BBC. "I am a good person. I am a student at university. I am a clean person. I don't do drugs."

"I never thought that something like that would happen to me," she said.

Bella is now around eight months pregnant, but the identity of the father has not been revealed.

Georgian prosecutors say she was carrying 12kg of marijuana and 2kg of hashish in her luggage.

Bella initially pleaded not guilty at a hearing in July to possession and trafficking of illegal drugs.

She's spent the last almost six months in pre-trial detention in Georgia's Rustavi Prison Number 5 — where her mother told BBC she had only a hole in the ground for a toilet, one hour of fresh air daily and communal showers twice a week — before being moved to a "mother and baby" unit.

In October, Bella's family confirmed they paid £137,000 ($275,000 AUD) to reduce her sentence.

Initially, her sentence was set to be reduced to two years. However, on Monday, Bella was released from prison after prosecutors made last-minute changes to the plea deal.

Instead, Bella was sentenced to the five months and 24 days she had already served in jail in the South Caucasus country.

Flanked by her mother and lawyer outside the courthouse moments after being released, the teenager said she had not been expecting to walk free, and was "happy and relieved" at the news.

Bella is due to return home within days.

The case prosecutor, Vakhtang Tsalughelashvili, said authorities had adjusted Bella's plea agreement after taking into account her young age and pregnancy.

"We are very grateful that they took Bella's situation and financial condition into consideration," Culley's lawyer Malkhaz Salakaia told reporters.

Her release comes at a time when Georgia is tightening penalties for drug-related offences.

Drug smuggling carries a prison sentence of up to 20 years in Georgia.
