CCTV footage has been released of three armed robbers forcing their way into a bank in Northamptonshire.

The film shows two security guards trying to stop the men from entering Nationwide in Rothwell on 26 November.

Once inside, the men attacked one security guard with a crowbar before stealing a substantial amount of cash.

Northamptonshire Police hope the footage will encourage anyone with information to come forward.
