AN INVESTIGATION is underway after an armed robbery at a Co-Op store earlier today.

At around 6am on Sunday morning, two balaclava clad men, one carrying a hammer and the other carrying a machete entered the store on Merrytrees Lane, Cottam, and started threatening staff, demanding one lay down on the floor while forcing the other to provide access to a safe.

The men escaped with cash and thousands of pounds worth of cigarettes, with police called at around 6.15am.

Preston CID Detective Inspector Lee Richardson said: "This incident was very scary for the staff involved and they have been left badly shaken, but thankfully unhurt, following their ordeal.

"We believe this robbery was well planned and prepared.

"The offenders arrived prior to the store opening and were keen to access the safe and cash boxes.

"We believe those involved will have been in and around the area in recent days and weeks to establish routines around the store opening.

"Did you see a car in the area with two men inside which seemed out of place?

"Given the time of day, it is possible early workers or dog walkers might have some information.

"If you think you can help us please come forward."

Anyone with information can call police on 101 or email 270@lancashire.police.uk quoting log 0401 of January 23.

Alternatively witnesses can contact independent charity Crimestoppers anonymously by calling 0800 555 111.
