A man has been arrested after a robbery of a Co-op store in which staff were threatened with a weapon earlier this week.

The Co-op branch in Blackburn Road, Darwen, was robbed on Monday, June 20, at around 8.25pm when a man went into the shop, threatened workers and demanded money before fleeing with an undisclosed amount of cash.

Following an investigation police announced on Friday that a 27-year-old man had been arrested in connection with the incident.

A police spokesperson said: “Further to our earlier appeal following a shop robbery at the Co-Op in Darwen on Monday, a man has now been arrested by police.

“A 27-year-old man from Darwen has been arrested on suspicion of robbery and is in custody.”

Officers launched their appeal earlier this week after the robbery.

They say that the man had picked up a case of lager from a display stack near before approaching the check out.

After placing the case on the till area, he produced a weapon and threatened a staff member.

He then forced his way into the till area, demanded money before taking an undisclosed amount of cash and fleeing from the shop.

No other arrests have been reported in relation to the incident.
