Mohammed Emwazi, the British graduate named as Islamic State murderer "Jihadi John", was a model worker who was "very good with people", his former employer has said.
The manager of an unnamed IT firm that hired Emwazi as a salesman while he lived in the Gulf told the Guardian he was "the best employee we ever had".
"How could someone as calm and quiet as him become like the man who we saw on the news? It's just not logical that he could be this guy," he said.
"I have no answers for this. He wasn't sociable. He was always earnest. He didn't smile. But he wasn't bad."
He said Emwazi had left the company when he returned to England in 2010, adding: "Maybe he fell into the wrong hands when he went back."
