It is reported that the offender was carrying a firearm, and after leaving the shop, he allegedly ran in front of a lorry which had to make an emergency stop.

Police have stated that no one was injured but the man made off with a small number of mobile phones.

The offender is described by Thames Valley Police (TVP) as a black man, around 5ft 6ins tall, skinny build, wearing a black hoodie, black tracksuit bottoms and wearing a black mask.

He was also carrying a black backpack.

It comes as the TVP Cherwell Facebook page released a cryptic message on Saturday afternoon which left many wondering what the circumstances were behind the helicopter.

The post said: "Dear Banbury, yes the helicopter is up. No, it’s not for the football. We may update you later."

Chief Inspector Rob Platt, said on Sunday: “This was a concerning incident as such we are carrying out a thorough investigation.

“As such we are asking anyone with information to please come forward, particularly anyone who may have CCTV or dash-cam footage.
