A post-mortem examination will take place in due course.<br /><br />Bristol Commander, Supt Mark Runacres, said: “Tragically, we have lost another young life from our city in utterly horrific circumstances.<br /><br />“Our thoughts are with the victim’s family at what will be an unimaginably difficult time and officers will continue to support them.<br /><br />“We are committed to bringing those responsible to justice and we will be working tirelessly to that end.<br /><br />“While we are keeping an open mind, there is no clear evidence to suggest this is linked to other recent incidents in the city.”<br /><br />The A420 was closed between West Street and the Lawrence Hill roundabout to allow crime scene investigators to examine the scene but has since reopened overnight. A cordon remains in place in Rawnsley Park.<br /><br />Officers continue to make enquiries this morning, including reviewing CCTV footage and there will be increased patrols in the area.
