A man and woman have been arrested after security guards were threatened with a sledgehammer and crowbar when delivering cash to a Lancashire bank.
The guards were at Abbey Santander in Padiham, at 2315 BST on 8 June, when they were attacked.
The robbers also smashed their way into the bank before fleeing with a "significant amount of cash", Lancashire police said.
A man, 21, and woman, 20, from Salford, were arrested on suspicion of robbery.
They have been released on bail until November, pending further inquiries.
