Abdel-Majed Abdel Bary, 24, was known as L Jinny or Lyricist Jinn at home in London, where his rising music career saw him appear in videos and have his singles played on BBC Radio in 2012.

He came to national attention earlier this year, when he posted a picture of himself holding a severed head on Twitter after resurfacing in Syria.

The gruesome picture, believed to have been taken in the Isis stronghold of Raqqa, was captioned: “Chillin’ with my homie or what’s left of him.”
