Abdel Bary attained considerable notoriety as he emerged as a prime suspect in the hunt for "Jihadi John",[2][3][4][5] but in February 2015, it was reported that the executioner was Londoner Mohammed Emwazi.
After a very long process of investigation, with the possible return of Adel Abdel Bari to Egypt, he was extradited eventually by the British authorities to the United States in 2012 for involvement in the 1998 United States embassy bombings in Kenya and Tanzania and for having alleged links and a longtime association with Osama bin Laden and more prominently Ayman al-Zawahiri, former leader of al Qaeda.
On 6 February 2015, Adel Abdel Bari pleaded guilty and was sentenced to 25 years in prison – the plea bargain was described by the judge as generous.
In lyrics for earlier releases online going back to 2012, Bary made apparent references to drug use, violence and life on a council estate[6] and talked about the threat of his family being deported to Egypt due to his father's terrorist activity.
In later songs, however, references to cannabis use stopped in his lyrics to be replaced with more radical tirades against people who choose to spend their money clubbing, drinking and on drugs rather than feeding their families.
Known tracks by him include "Overdose" (the only one uploaded, now removed, to his YouTube channel LJinnyVEVO), "Flying High", "Dreamer", "The Beginning", and "Dog Pound."
In June 2014, The Sunday Times revealed a threat made by Bary on Twitter saying: "The lions are coming for you soon you filthy kuffs (infidels).
[5][13] In February 2015, it was confirmed that "Jihadi John" is not Abdel Bary, but actually Mohammed Emwazi, a Kuwaiti-born man in his mid-20s who had left West London to join ISIS.
Bary also claimed that he and Junaid Hussain were kidnapped, tortured and robbed by members of a rival Islamic terror group.
[18] On 12 July 2023, he was put on trial in Soto del Real, Madrid on charges related to membership of ISIS as well as using online scams to raise funds for terrorist activities.
