The alleged leader of the cell, Abid Naseer, who is 28 and from Pakistan, was a studying in Britain in April 2009 and was arrested by British police along with 12 others for planning a series of suicide bombings in the city of Manchester. He was extradited to the US in 2012 to face changes of organising a suicide attack against the New York public transportation system.
The US prosecutors claim Naseer had received paramilitary training in Pakistan before moving to the UK, where he was planning to carrying out terrorist attacks in the UK .
Last year, the US prosecution asked the judge to allow six British intelligence officers (from MI5), who had been monitoring Naseer’s activities before he was eventually arrested to provide vital evidence in the US court in secrecy without disclosing their identities due to the security officers still remaining active in counterterrorism investigations. The judge agreed, and the first of the six MI5 officers gave evidence this week through a video link from an undisclosed location in the Britain.
One of the MI5 officers who appeared concealed his identity by wearing a false goatee beard, thick spectacles and what reporters described as “a long black wig”. He was also wearing heavy make-up and was identified in court only as “serial number 1603”, according to British newspaper The Daily Telegraph.
The operative informed the court that he was part of a team of MI5 surveillance officers who closely followed Mr. Naseer for over a month while he was allegedly planning suicide operations in Britain and the US. The surveillance included following the suspect as he was scouting targets in Manchester and monitoring his travel on public transport one one occasion when the suspect was traveling by bus from Manchester to Liverpool. Mr Naseer is defending himself in the trial and had the chance to cross-examine the MI5 officer, said The Telegraph.
