Man arrested over 'disseminating terror publications'
A 30-year-old man has been arrested in east London on suspicion of disseminating terror publications.
The arrest is linked to the investigation into Ibrahim Abdullah-Hassan, who was charged last week with terror offences.
Mr Abdullah-Hassan was arrested at the BBC after giving an interview about one of the men accused of murdering soldier Lee Rigby in Woolwich.
The charges against Mr Abdullah-Hassan do not relate to the Woolwich murder.
The man arrested on Wednesday was taken to an east London police station, where he remains in custody.
Officers from Scotland Yard's Counter Terrorism Command have also been carrying out searches of a house and a vehicle.
The specialist unit made the arrest as part of the investigation into Mr Abdullah-Hassan, also known as Abu Nusaybah.
Mr Abdullah-Hassan, also 30 and from east London, was arrested on 24 May after giving an interview about his friend Michael Adebolajo on the BBC's Newsnight programme.
He was later charged with three terror offences, which he denies, relating to videos of lectures and written material.
He was remanded in custody at Westminster Magistrates' Court and will appear at the Old Bailey on 28 June.
