It made me jump! It was a surreal moment, it’s not something you were expecting to happen.I was just getting out of my car in Barking, Colin McMillan was fighting there. I was getting out the car and I heard a bang. I thought it was a car backfiring.I looked around and I’ve seen somebody standing there holding a gun.First of all I thought it was a joke, I was looking around and I thought, ‘What’s all this about?’I could see him shaking a bit, then there was a click and I realised there was another bang and I felt pain in my side.“What had happened, it had gone in my chest and I was standing at an angle and thankfully it went through my lung – and I lost half a lung – and came out.A friend of mine, a barrister called John Buttress, he went, ‘What the f*** are you doing?’ And he jumped on him.I didn’t realise, I suddenly felt this gurgling in my throat and because obviously the blood through my lungs had got into my throat.And then I was losing my breath, I went down on one knee and then I remember my late uncle Bob coming out and my brother Robert.They were standing over me, they were helping me and they said, ‘Get a doctor, get a doctor.’At every show we have doctors and the Boxing Board of Control’s doctor came out. I remember him saying, ‘Have you got a hankerchief?’I said, ‘Yeah,’ and he said, ‘Hold it on.’At the time the ambulances were all on strike so the next minute they bundled me into the back of a police van.They done like a 16-point turn up the curbs and everything.And they drove me off to the hospital and that was it.*Warren was speaking to talkSPORT…CASINO SPECIAL – BEST CASINO WELCOME OFFERS“But also I think he’s enjoying the fruits that it brings to our business, and our sport and our fighters.”Warren survived the murder attempt as a 9mm bullet – from a Luger pistol – missed his heart by just an inch.Jake Paul knocking out Mike Tyson, 58, would be a ‘travesty’ and no real boxing fan wants to see it, blasts Eddie HearnHe did lose half a lung and parts of his ribs and was unable to promote for over a year – forcing his business into liquidation.Boxer Terry Marsh – who was involved in a legal dispute with Warren – was arrested and charged with attempted murder on his ex-promoter.
