He was further questioned in relation to allegations about aiding and abetting a terrorist organisation as well as his participation in several illegal demonstrations on behalf of this terrorist organisation and several incidents of assault and battery. He was further asked questions about a co‑accused’s incriminating statements. 8.  On 2 November 2009 the public prosecutor questioned the applicant in the presence of his lawyer.
