Mohiussunnath Chowdhury, a former Uber driver who has been found guilty of planning terrorist attacks told police officers he 'learned a lot' from 'likeminded' Streatham attacker Sudesh Amman while in Belmarsh prison.
Chowdhury, 28, had previously been cleared of a sword attack on police outside Buckingham Palace, but was convicted at Woolwich Crown Court on Monday and had allegedly boasted to undercover police how he had deceived a jury into finding him not guilty of the attack.
Sneha Chowdhury, 25, his sister, cried as she was also convicted of one count of failing to disclose information about acts of terrorism and cleared of another count of the same charge.
The Court heard Chowdhury unwittingly revealed his plans to 'unleash death and suffering on non-Muslim members of the public' to undercover agents and had 'learned a lot' from 'likeminded brothers' whilst on remand at Belmarsh with other terrorists which included Streatham knife attacker Sudesh Amman, 20, who was shot dead by police officers after stabbing two people in Streatham High Road on Sunday 2 February.
His defence barrister Simon Csoka QC had argued the university drop-out was a 'pathetic little man' and an 'attention-seeker' who 'talks and talks, but doesn't do'.
While being interviewed by police, just three days before a Pride event in London, he appeared 'personable'.
Prosecutor Duncan Atkinson QC said Chowdhury desired to 'unleash death and suffering' on non-Muslims after absorbing sermons from preachers like al Qaida's Anwar Al-Awlaki.
Chowdhury from Luton was 'motivated by dreams of martyrdom for the cause of Islam, and inspired by preachers of hate', a jury at Woolwich Crown Court was previously told.
The brother and sister today hugged in the dock and Chowdhury, dressed in a blue shirt and tie, could be heard whispering: 'It's all right.'
He will be sentenced by judge Andrew Lees on March 13 while she was bailed for a pre-sentence report to be prepared.
The extremist, who had martyrdom notes posted on his bedroom door, had the intention 'to kill and harm as many people as possible', Scotland Yard counter terror commander Richard Smith told reporters.
Chowdhury told one undercover officer known only as Mikael he was free to attack one million unbelievers if he was fighting for 'the pleasure of Allah' and stressed the importance of an 'ambush', saying: 'They shouldn't know what hit them', the trial heard.
According to reports Chowdhury later added during the conversation: 'It must be an ambush ... we should be the one doing it first, they shouldn't know what's hit them, yeah, does that make sense?'
The court heard how Chowdhury had bragged about deceiving the jury which cleared him at a previous trial at the Old Bailey in December 2018 for the palace sword attack including by shaving off his large unkempt beard.
