Mr Franklin said : 'We 've been told that an unknown man approached the group on the roundabout and threatened them . 'He was chased by several of the teenagers but produced a knife . 'One of the brothers was slashed across the chest and is lucky to be alive because the knife wound was so deep it was close to his heart . He was just a couple of millimetres from death .
