ARMED robbers threatened two security guards outside a supermarket before taking police on a high-speed chase across the country.

Two masked men threatened security guards delivering cash to the Co-op in Newton Drive, Thornaby, near Stockton, making off with thousands of pounds in cash.

The incident happened at about 7.55am yesterday.

The robbers then made off in a silver BMW Z4 before changing it for a red Honda Civic in the Vulcan Way area of Thornaby.

West Yorkshire Police spotted the vehicle on the westbound carriageway of the M62.

Greater Manchester Police took over the pursuit and finally stopped them in the car park of the Trafford Centre, in Manchester, at 10am.

A 31-year-old man was arrested and a handgun and a quantity of cash recovered.

The man is currently in custody helping police with their inquiries.

It is believed the robbers made off with about £2,000.

The two security guards were shaken, but not injured in the incident.

Both cars have been recovered and are undergoing forensic examination.

A Co-op worker said: “We heard about what was happening when a customer came in and told us. They didn’t come in here, but it has shaken us up a bit.

“We went out to see if the men were alright. They were bringing change for us when it happened.”

Detective Inspector Jon Green, of Cleveland Police, said: “Although we have made one arrest in connection with this incident I would still appeal to those who may have information to contact us, particularly anyone who may have information specific to the two cars involved.

“We do have information that the silver BMW Z4 may have been in the Thornaby area before yesterday and anyone who may have seen it is asked to contact us.”

A Cleveland Police spokeswoman said: “It’s believed that a handgun was used to threaten the security guard, but no shots were believed to be fired.”
