CCTV footage captured a vicious teenage gang thug kneecapping a man outside a shop in a "revenge attack".
In the shocking video clip, a series of three loud bangs can be heard before the victim, 33-year-old Michael Costello, shouts out in pain. Mr Costello is then captured hopping down the street on his right leg with a female companion in a desperate bid to escape.
Dark patches are visibly beginning to form on his left knee, but Mr Costello had also been shot in his right thigh with a patch of blood also showing there. In the background, two figures in dark clothing can be seen circling round before speeding out of shot on an electric bike.
