Police will not prosecute Palestinian academic Azzam Tamimi despite the fact that he told London students that he "longs to be a martyr, takes pride in being a terrorist," and that Israel "must come to an end".
Police began investigating after Dr Tamimi, director of the Institute of Islamic Political Thought in London, addressed students at the London's School of Oriental and African Studies' (SOAS) on February 9.
They handed the investigation over to the Crown Prosecution Service (CPS).
Dr Tamimi, often described as Hamas's spokesman in the UK, was on a national tour of student societies during the Federation of Islamic Societies Palestine Week.
A police spokesman said: "The CPS has reviewed all the material in this case and have advised that there is insufficient evidence to proceed with a prosecution against Azzam Tamimi, therefore the police will be taking no further action."
