Counter-terrorism police arrest man over extremist material Counter-terrorism police are believed to be investigating the arrested man over postings made on the internet. Counter-terrorism police have made a further arrest as part of an investigation into the dissemination of extremist material in the aftermath of the murder of Lee Rigby. The arrest follows the arrest and charge of Abu Nusaybah after an appearance on the BBC's Newsnight programme. Nusaybah, 30, from east London, has been charged with three terrorism offences. He was held after giving an interview about his friend Michael Adebolajo, one of the defendants charged with the murder of Rigby in Woolwich. The charges, which he denies, relate to videos of lectures and written material. The second man arrested is being investigated over postings made on the internet, it is understood. Nusaybah, who has been charged under his real name, Ibrahim Abdullah-Hassan, has been remanded in custody and is due to appear at the Old Bailey on 28 June. The charges against him include an allegation that on or before 24 May he published or caused another to publish five video recorded lectures entitled In Pursuit of Allah's Governance on the Earth, intending or being reckless as to whether members of the public would be encouraged to commit, prepare or instigate acts of terrorism. In two further charges, Abu Nusaybah is also alleged, on or before 24 May, to have provided services to others enabling them to access a video lecture by Khalid al-Husainan and a text called Reality of the Rulers by Abu Zubair Adil al-Adab, conduct which could be intended as a "direct or indirect encouragement to the commission, preparation or instigation of acts of terrorism," according to the Crown Prosecution Service's counter-terrorism unit. He was detained on 24 May outside the BBC's New Broadcasting House in central London, immediately after recording his interview with Newsnight. The latest arrest is not connected with the death of Rigby, who was murdered in Woolwich, south-east London, on 22 May. The drummer in the 2nd Battalion of the Royal Regiment of Fusiliers died of multiple stab wounds, a postmortem examination found. Michael Adebowale, 22, and Adebolajo, 28, have been charged with his murder. The number of arrests made in connection with the attack stands at 12. So far, eight people have been bailed and two released without charge.
