CSI spotted at Natwest in Blackpool after raiders 'smash their way inside'

Officers were called to the branch at 4.25am after the alarm sounded, with the force saying the raiders appear to have escaped empty-handed.

One witness said: "I was passing on the bus and I saw that, down the side alley, it looks like there had been an attempted break-in.

"The window had been smashed open big enough for someone to get through."

A spokeswoman for Lancashire Police said: "At this stage it doesn't look like anything has been taken, but we are still investigating."

Natwest has been contacted for a comment.
