A prosecution witness in the trial of Senator Mohammed Ali Ndume yesterday contradicted himself when he read to the court an International Mobile Equipment Identity (IMEI) number of a mobile phone which belongs to Ndume that was different from the digits he gave when he testified on Tuesday. The witness, Aliyu Usman, a forensic examiner attached to the State Security Service (SSS), on Tuesday told the court that the last four digits of the Nokia E7 ended with 3050, but when asked to read out the IMEI yesterday, Usman confirmed that the last four digits were 3055. On Wednesday, Usman told the court that there were 73 communications between the Nokia E7 with the IMEI 3050, which allegedly belongs to Ndume and the convicted spokesperson of the Boko Haram sect, Ali Sanda Umar Konduga, who allegedly owns the Nokia 2700 which has 9226 as the last four digits of its IMEI. Usman had told the court that in the cause of analyzing two mobile phones given to him by the chairman of the Special Investigation Panel (SIP), James Ene Izi, it was discovered that the duo had exchanged text messages, multi media messages and placed voice calls between October 3, 2011 and November 3, 2011. He said report of the findings as well as the call data records were burnt in three different DVDs and forwarded to the SIP chairman. Ndume's counsel, Rickey Tarfa (SAN), had objected to the DVD's being admitted in evidence but the court admitted same yesterday. Justice Gabriel Kolawale adjourned till January 16, 2013 for continuation of trial. Ndume is standing trial on terrorism-related charges before an Abuja Federal High Court.
