An investigation is underway into a crash that left four teenagers dead after they travelled to north Wales for a camping trip.
Wilf Fitchett and Hugo Morris, both aged 18, Harvey Owen, 17, and Jevon Hirst, 16, all from Shrewsbury, were reported missing after they failed to return home from a trip to Eryri, also known as Snowdonia, over the weekend.
