Australian accused drug trafficker Cassie Sainsbury has been sentenced to six years in a Colombian prison

Australian accused drug trafficker Cassie Sainsbury has been sentenced to six years in a Colombian prison.

The 22-year-old, who was initially facing up to 21 years incarceration, had her sentenced reduced after a judge accepted a plea deal.

According to the ABC, her lawyers say she should be able to get out in three years with good behaviour.

Along with the sentence, Sainsbury will also pay a fine of $US100,000 ($130,350).

The Adelaide personal trainer was arrested in April at Bogota’s international airport after 5.8 kilograms of cocaine was detected in her luggage.

She later said she thought she had accepted a job as a legitimate courier transporting documents but when plans changed the last minute, she was sent to Colombia where a “mastermind” known only as Angelo threatened to kill her family if she did not transport his drugs.
