ISIS beheading expert Jihadi John flees: Reports
"ISIS would drop him "like a stone or worse if they feel he is no longer of any use to them," The Express reported.
According to reports, "It is possible he will end up suffering the same fate as his victims".
Identity of Jihadi John was revealed by The Washington Post and the BBC in February this year. He was identified as Muhammed Emwazi born in Kuwait and raised in Britain. He became the infamous covered face of the beheading videos of the ISIS.
The 26-year-old, whose first ISIS video came in August 2014, is typically dressed with a black wrap covering his entire face, with only his eyes peeking through.
US led coalition is reportedly looking for him for the murders of journalists Stephen Sotloff and James Foley and aid workers David Haines, Alan Henning and Peter Kassig.
Reports also claimed Emwazi may become target for fellow ISIS members who are envious of his notoriety.
To maintain a low profile, Emwazi is likely to have joined a less well-known extremist group in Syria.
