A British teen was arrested at Miami International Airport after authorities say they found 30 pounds of cocaine stuffed into 24 boxes of cake mix in her suitcase. Ayesha Olivia Niles, who turned 18 three days after she was arrested on Oct. 21, faces charges of trafficking cocaine and importation of a controlled substance, according to the Miami Herald. She was being held in Miami's juvenile detention center but will likely be charged as an adult, prosecutors said. The London teen had arrived in Miami on a flight from Jamaica. Federal customs agents made the discovery after her bags were selected for screening."

In Florida, drug-traffickers can get sentenced to life in jail, which means a minimum tariff of 15 years.

Niles, a student from London, told police she did not know what she was carrying but suspected she was involved in illegal activity.

Police said the teen, who is from London, was picked for screening by customs agents.

As they searched her two suitcases they found the class A drug hidden in the boxes of cake mix.

It is not known if Niles was planning to continue with the drugs back to London are drop them off in Florida.

A police source said: 'She is a classic drug mule who thought she could easily bring the drugs through an airport undetected.'

Prosecutors said Niles was a 'poster child' for how easily drug smugglers can corrupt young people.

'This young woman had her 18th birthday in a foreign jail, far from her home and her family, because she thought she could smuggle almost 30 pounds of cocaine through Miami,' said Miami-Dade State Attorney Katherine Fernandez Rundle.

'Sadly, she almost becomes a poster child for how easily the drug trade can corrupt our youth.'
