The Ghanaian/Austrian lady arrested by UK authorities with 12.5 kilos of cocaine at Heathrow Airport may be contemplating vacating her earlier guilty plea.

Nayele Ametefe pleaded guilty to exporting narcotic drugs to the United Kingdom on her first appearance in court on November 27, 2014, following her arrest.

But a former Senior Crown Prosecutor in the UK, Godwin Adjei-Gyamfi, in a Facebook post, said, "A call was made to the court on the 2/01/15 that she indeed wishes to vacate her guilty plea. The court is yet to inform the CPS (Crown Prosecution Service) formally because the staff who received the call is not sure of the authenticity of the call."

Nayele was due in court today, but hearing was postponed to Tuesday, January 6, 2015 because prosecutors could not complete a forensic evaluation of the purity of the cocaine.

She was expected to be sentenced at the next adjourned date.

If the call is authenticated as coming from Nayele, the case may be taking a dramatic turn.

"If she maintains her early guilty plea, she is looking between 9-10 years with a discount for early guilty plea. However, if she fights the case and she is found guilty she may be looking at 13 years," Mr. Adjei-Gyamfi stated in his facebook post.
