According to 9 News, a man planned to smuggle more than 600 grams of cocaine into Brisbane, but he revealed the secret because of abdominal pain.

French citizen Adrien Lionel van Langenhove admitted to bringing the drugs into Australia to repay the A$5600 commercial debt he owed during his work and life in Costa Rica and Guatemala.

He arrived at Brisbane International Airport on December 2017, 12. Customs officers searched him and found traces of cocaine in his luggage.

However, the customs officers failed to find the drugs and were helpless to release the man.

However, shortly after leaving the airport, Van Langenhove had unbearable abdominal pain and asked a pharmacist for help.

In the end the pharmacist helped him call an ambulance and took him to the hospital.

Through surgery, 86 pills containing 637 grams of cocaine were removed from the man's body.

Van Langenhove was arrested by the police when he was discharged from hospital and pleaded guilty in the Brisbane Supreme Court on Monday, pleading guilty to importing a large amount of border-controlled drugs.

He was sentenced to 7 years in prison, with a non-parole period of 4 years.

The court learned that he had gone to work in Australia earlier in 2017, and his display of wealth caused creditors to pressure him to repay his debts.

His lawyer stated that Van Langenhove agreed to carry drugs out of concerns about his own safety.
