POLICE have been inundated with calls about loud bang, believed to be a series of sonic booms.
Fire crews are also investigating the source of the noise and Oxfordshire Fire and Rescue are liaising with neighbouring counties.
Thames Valley Police duty inspector Phil Rogers said people have reported the noise, from Chipping Norton, Burford, Banbury and North
Newington, right out to Swindon and Warwick.
He said: “There have been no reports of any casualties or damage.
“We believe it could be a sonic boom from a supersonic aircraft.”
He added that he believed it to be more than a single incident as the reports were so far spread.
Some have reported the noise was so loud it ‘shook their house’.
