A customs officer will not undergo a retrial on allegations that he plotted to import cannabis after a prosecutor filed an application to discharge the matter this morning.Bromwin Thompson had been awaiting a decision on whether he would go on trial again since April, when a jury failed to reach a verdict on one drug charge and cleared him of another.Mr Thompson, 36, was accused of conspiring with his friend, fisherman Shannon Berkley, 42, to import $54,725-worth of drugs in packages discovered after they arrived on the Island via courier in 2009.Mr Thompson was working at the FedEx courier facility in Serpentine Road, Pembroke, at the time.Prosecutor Nicole Smith presented the jury in his trial with phone records she said demonstrated how he and Berkley exchanged information about the packages.She alleged Mr Thompson's role was to look out for them and intercept them.The drugs were discovered when one package, mailed from New York, was highlighted as suspicious after Mr Thompson X-Rayed it twice at the FedEx facility in Serpentine Road and the results were inconclusive.He was instructed by a more senior officer to open it up, and drugs were discovered inside.A second package of drugs, mailed from Ethiopia, was discovered by a sniffer dog at the FedEx facility at the airport.Prosecution witnesses described seeing Mr Thompson pay two unauthorised visits to the airport facility when courier packages were being unloaded.However, he protested his innocence during his Supreme Court trial, insisting he had no idea what was in the packages.He admitted Berkley contacted him to ask him to look out for the New York package, but said there was nothing unusual in a friend asking him to do this as it happens regularly.He said although Berkley's phone records demonstrated Berkley knew address details relating to the Ethiopia package, he had no knowledge of that parcel.Mr Thompson said whenever he'd visited the airport facility, it was done on the instructions of a superior officer.The jury cleared him over the Ethiopia package, but could not reach a verdict on the New York parcel after deliberating for more than four hours. Prosecutor Ms Smith said she would apply for a retrial on that charge.However, this morning, prosecutor Kirsty-Ann Kiellor filed an application to discontinue that matter, which was agreed by Puisne Judge Carlisle Greaves.The judge told Mr Thompson: "Defendant you are discharged in respect of count one."Mr Thompson, from Southampton, who had been working as a customs officer since 2003, told the jury during his trial that he is no longer employed by HM Customs.Berkley pleaded guilty prior to Mr Thompson's trial to cannabis importation. He is due to be sentenced on July 8.
