Police hope a television appeal about an armed bank robbery in which officers were shot at will prompt fresh leads. The gang fired at a police van as they made their getaway from Barclays Bank in Horwich, Bolton, in November, after assaulting three bank workers.
A reconstruction of the raid was shown on BBC One Crimewatch programme on Thursday evening.
It also featured the account of a female staff member who was attacked by the gang.
CCTV footage from the robbery showed masked men - armed with shotguns and machetes - running into the bank on 29 November.

One of the bank's staff is seen being dragged around by the men.
The pair fled with a large sum of cash and later fired at a police van's windscreen.
Det Ch Insp David Law, of Greater Manchester Police, said: "We have been working closely with the Crimewatch team over the last couple of weeks to reconstruct the terrifying incident at the end of last November.
"I'd encourage everyone in the local community to watch the programme.
"It may bring back memories of something that you may have felt was insignificant at the time but could now hold the key to solving this crime."
A reward of �50,000 is being offered for information leading to the arrest and conviction of the offenders.
