Jacob Hallam QC: CCTV footage shows Mr Pomeroys' “hands go out towards defendant after blow to his neck."
DC Marc Farmer says it “looks like he (Pencille) is folding the knife away” after attack. CCTV shows Pencille waiting by the door after the "frenzied attack" for the train to stop at Clandon station.
Multiple train cameras show the attack from different angles. Lee Pomeroy’s bloodied face is visible as he is repeatedly stabbed. Darren Pencille is then shown collecting his belongings from the carriage floor which was covered in blood & leaving the train at Clandon station.
