[citation needed] In December 2013, Hussain went to the police station in the town of High Wycombe and told officers that he intended to travel to Syria from Turkey with an aid convoy.
[citation needed] Hussain's nom de guerre, Abu Sa'eed al-Britani, was found etched on the wall of a cell in the IS prison underneath the stadium at Raqqa.
[10] Although it was reported that most captives of the prison did not survive their detention, the date beneath Hussain's name is 24 February 2016 - more than a full year prior to his actual disappearance and last activity on social media.
[citation needed] Abu Sa'eed spent approximately two months in ISIS dungeons at that time, but made it out and participated in the Battle of Raqqa.
[11] On 18 August 2019 it was reported by some British newspapers, citing "security sources", that Hussain had died in an Islamic State suicide attack during the Battle of Raqqa.
