On Nov 6 2010, Mr Perepilichnyy left for Paris, returning home on Nov 10, the day he died. A source close to the investigation said: “Perepilichnyy had just come back from Paris on the day he died. He had arrived in the morning on the Eurostar [train] and gone home but begun to feel unwell. He went for a jog to shake it off and collapsed and died.
