Prosecutor said Ashley Facey is the only eyewitness in this case and was a close friend of Sean. Ashley Facey, 23, today faced cross-examination in Cardiff Crown by Prosecutor Quinlan.Ashley Facey, said: “I saw Bingham drop his bike and pull out a knife from his waist with his right hand.Ashley described in court how Sean started running but tripped over a bin and fell on his front, he flipped over, laying on his back and starts kicking his legs out of defence.Mr Facey said: “Bingham bent over him and stabbed his leg at least three times.”Ashley added: “I heard a voice saying ‘jook the other one’ “Jook is street slang for cut, slice, or stab.”Ashley explained in court how Sean got up on his feet and they both ran down Broadway.Facey said: “They chased us on their bikes and the first thing that came to my head was my little one-year-old son.”And I knew that the next thing that was going to happen was stabbing me.”Footage from CCTV cameras was shown in court of Aaron and Nicholas biking towards the crime scene.Mr Quinlan said: “They were acting together in a joint attack.”Mr Bingham stabbed Mr Kelly at an age of 18.”And Mr Saleh participated in the fatal attack.”A neighbour of Theodora Street, Casey Wozencroft, said she heard a man with a Cardiff accent shout “I will fucking kill you” and another neighbour heard “I’m going to slice him up”.
