Police have reopened the A1 in North Yorkshire after it was closed for more than 12 hours following reports of an explosion.
It was shut between Leeming and Barton as a precaution while police investigated reports of a blast near Marne Barracks at 3am this morning.
Eight people told police they heard an explosion - but officers say after extensive searches of the area, they've found no obvious signs of a blast.
North Yorkshire Police, the North East Counter Terrorism Unit, explosives detection dogs, the National Police Air Service and military search personnel have all been involved in today's searches.
We are satisfied that the call to the police was made with good intent.
“We appreciate that members of the public will ask why the road had to be shut for so long.
"In view of the location of the suspected explosion, the source of the information, the current threat to UK security and a report a few hours earlier of a vehicle seen in suspicious circumstances outside the barracks, we were not prepared to take any chances with people’s safety and had to carry out a very extensive and thorough investigation.
“We may never find out what the source of the explosion was, however, following the search and investigation I am now satisfied that there is no threat to members of the public. A number of possibilities have been looked into, however, there is no information or evidence to say this reported explosion was a criminal or deliberate act.”
Police investigating reports of an explosion in and around CatterickGarrison says they have found a number of ageing detonators alongside the A1 adjacent to Marne Barracks.
These detonators are being removed by the army’s bomb disposal team to a safe area where a controlled explosion will take place.
However a police spokesman insists that the detonators were NOT the cause of the original explosion reported by staff at the Marne Barracks at 3am.
The search for the source of that explosion continues and the police say that the A1 will reopen when it is safe to do so.
The road has been closed in both directions in the Catterick area since 3am.
A spokesman for the Highways Agency said the closure on the A1 in North Yorkshire is now expected to remain in place until between 5.30pm and 6pm.
Earlier today they had anticipated that the road would re-open at around 3pm.
Police are continuing the search for the source of an explosion reported by staff at the Marne Barracks, in Catterick, at 3am.
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.
