Detectives have released CCTV video of an armed raid at a bank in Greater Manchester where the robbers shot at police as they tried to escape.
The robbers fired at a police van as they made their getaway
The footage shows masked men - armed with shotguns and machetes - running into Barclays on Winter Hey Lane in Horwich, Bolton, on 29 November.
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.
The British Bankers' Association has offered a £25,000 reward
As the police van drew up behind the Mondeo, one of the robbers got out and fired at the windscreen of the van with a shotgun.
A 26-year-old police officer suffered facial injuries from flying glass and his 40-year-old female colleague suffered shock.
The two Horwich-based constables - who were unarmed - were taken to the Royal Bolton Hospital after the attack and later discharged. The assaulted staff member was treated by paramedics.
The three men, who are all believed to be white, were wearing dark clothing and dark-coloured face masks.
