Police say they still haven't managed to locate the site of an explosion close to Marne Barracks in Catterick.
Staff at the Barracks reported hearing an explosion around 3am, but the search for where it happened has been hampered by darkness and poor weather.
The search remains focused on the area outside of the barracks and the area next to the A1 although police they can't rule out the possibility it happened within the boundary of the barracks.
The safety of members of the public, including passing motorists, is our prime concern and therefore all security precautions must be taken to protect members of the public until we find out exactly what has occurred.
