SHOP workers were left terrified after men armed with knives and machetes demanded cash from them at a petrol station.

Police said a silver Nissan Juke pulled up to the rear of the petrol station at Asda near Princess Way, Burnley, on Saturday at 10pm.

Three men, armed with knives and machetes and wearing balaclavas, walked up to the shop workers, two women and a man, who were closing the shop at the time and demanded money from them.

One of the men pulled a rucksack off one of the women and caused her to fall over and suffer injuries.

The men left the shop and are believed to have driven away in a black Audi A1, which was found abounded nearby on Holme Road.

Police said both of the cars had been stolen from a house in Padiham earlier that evening.

Det Con Andy Lever said: "This has been a truly terrifying experience for the people involved.

"Luckily nobody suffered serious harm, but we need to find the people responsible as quickly as possible.

"If you witnessed the incident or saw anything suspicious in the area, we need to hear from you.

"We believe the Nissan Juke may have been in Asda car park between 9:30pm and 10pm when the offence occurred.

"If you saw either vehicle prior to or following the incident, please let us know.

"We would particularly like to speak to anyone who has dash cam footage who was in the vicinity of Asda car park between these times.”
