After being raised as a Jehovah’s Witness, Ziamani converted to Islam in April last year and was kicked out of home as a result.
He slept rough outside St Thomas’s hospital and said he found comfort in his new faith.
Ziamani’s girlfriend split up with him after he described one of the killers of Lee Rigby as a legend.
Ziamani attended a meeting of proscribed terrorist group Al-Muhajiroun (ALM), set up by Anjem Choudary, in the basement of a Halal sweet shop in East London.
The troubled teen then started putting extremist posts on his Facebook page including: “Sharia Law on its way on our streets we will implement it its part of our religion we will get Dem kufar soon we r soldiers of Allah TAKBIR” and “Land of democracy = Evil.”
Ziamani posted: “Why are They acting like Lee Rigby’s death was the worse death ever he just got run over n stabbed left right centre I bet if n Englishmen did it they wont say nuffin or make a big deal over it but two Muslim brothers run over dis kaffar n now making a big deal.”
Ziamani used his phone to visit websites researching the locations for army cadet bases in Camberwell and Lewisham and viewed the websites for the London Irish Rifles Association, which is based in Flodden Road, just minutes away from where he was living.
Counter Terrorism Command searched Ziamani’s address in Warner Road in relation to the unnamed tenant illegally subletting his premises to Ziamani and one other.
A letter discovered in Ziamani’s trousers exposed his extremist intentions to commit a terrorist act.

Ziamani posted a picture of six decapitated heads arranged in a row on the ground.
Ziamani searched online for detailed information about the murder of Lee Rigby and watched YouTube footage of the attack.
Ziamani turned up at his ex-girlfriend’s home and said: “If I leave this world I don’t want any hatred to be left between us.’

While on remand at HMP Wandsworth, Ziamani told a security officer that he ‘loved’ Lee Rigby killer Michael Adebolajo and added: “I was on my way to kill a British Soldier at an army barracks.
“I was going to behead the soldier and hold his head in the air so my friend could take a photograph.”
