Armed robbers attacked staff at Barclays Bank in Horwich, near Bolton, before fleeing with cash. They later blasted a police van with a shotgun as they made their escape. See dramatic footage of the bank raid here.
After assaulting staff, the pair fled with a large sum of cash and later fired at a police van's windscreen.
A £25,000 reward is offered for leads which will result in their conviction.
The pair raided the bank at about 0930 GMT and escaped in a red Ford Focus driven by a third man.
They later set fire to it and got into a silver Ford Mondeo just off Crown Lane.
