Quick-thinking staff at two Kettering shops foiled a pair of sawn-off shotgun-armed robbers who struck shortly before Christmas.
Police are now on the hunt for the duo, who tried to rob a Tesco Express store in Windmill Avenue at 12.15am on Friday, December 20, and then the Co-op food store in Stamford Road at 6.30am on Monday, December 23.
A quick-thinking manager at the Co-op food store was able to foil the pair when he spotted them approaching the rear of the store wearing face coverings and carrying the firearm.
A spokesman for the firm said: “The manager immediately sealed the entrance and the men fled.
“We are working with police and are constantly reviewing our security measures at stores in the area.”
Police said the manager at the Tesco store had also prevented the robbers from stealing anything by locking himself in a toilet inside the store.
Officers have also visited other nearby shops to offer advice and warn them about the incidents.
Det Insp Ali Reynolds said: “Armed robbery is a serious offence that carries a penalty of up to 10 years in prison. We are appealing for anyone with information to contact police.”
