A NIGERIAN whose girlfriend asked him to store more than two kilograms of heroin valued at $2.4 million was jailed for 14 years yesterday in the High Court. Nnamdi Beluchukwu Ezeike, 31, a trader in children's clothing in Lagos, admitted to trafficking in 2.63 kg of a mixture containing 2.35 kg of salts of esters of morphine. In sentencing him, Deputy Judge Wong took into account Ezeike's guilty plea but pointed to the drug's high level of purity, listed as No 4 heroin. Senior Crown Counsel Christina Ma told the court that on December 11 last year, the defendant was approached by customs officers in Mody Road, Tsim Sha Tsui. They found the drugs inside the lining of a travel bag he was carrying. The court heard that Ezeike had been in Hong Kong for a month before his arrest. He had arrived on business soon after his marriage to a university student in Lagos. Defence counsel Luke McGuinniety said it was a sad story of a ''stupid-minded courier'' who agreed to keep the drugs in his room in a guest house in Chungking Mansions for US$500 (HK$3,862). Mr McGuinniety said Ezeike struck up a relationship with a Bangladeshi woman who, with a friend, asked him to store the drugs for a couple of nights. He reluctantly agreed after he was told he would be paid.
