In London: Teenage Briton admits inciting terrorism in ANZAC day plot

The boy, who can’t be named because of his age, was arrested in north-west England in April.

He attended court by video link from Manchester, where he was accompanied by his father and sat listening to proceedings wearing a striped tie, grey shirt and glasses.

The teenager will be back in court in Manchester in September for sentencing.

The second charge of beheading was dropped by prosecution yesterday.

Judge Mr Justice Saunders ordered pre-sentence reports to find out if the boy had been indoctrinated.

The boy was initially arrested on 2 April in connection with an alleged plan to stage an attack in Melbourne and was detained again after officers examined electronic devices and discovered his communications with a man in Australia.

The charge related to the incitement to murder police officers during an attack on a parade marking ANZAC Day – a day of remembrance in Australia and New Zealand.

The ISIS-inspired attack was due to be carried out during a parade on Anzac Day, or April 25, when Australia commemorates the wartime service of its armed forces.

Prosecutor Paul Greaney QC said the charge related to 10 days in March when he and the Australian youth were in constant contact, sharing their Islamic State admiration and the need for jihad.

Greaney said that as part of their preparations “the defendant sent Sevdet Besim a message that read, ‘suggest you break into someone’s house and get your first taste of beheading”‘.

According to prosecutors, the teenager encouraged Besim to run down police officers with a auto and behead them with a knife before shooting others.

“The messages also set out the plotters” preparations for the attack.

Police in the UK were informed of the involvement of the 14-year-old British suspect earlier this year while the Australian authorities investigated the death of another Isis supporter, Besim’s friend Numan Haider.
