ARMED robbers struck at a Brighouse bank in a virtual replica of an attack exactly seven weeks earlier.
Police have not yet linked the two raids on Santander, but said they are not ruling out a possible connection.
In the latest incident, three men in balaclavas drove to the Commercial Street bank in an old Ford Mondeo car at about 7.10pm on Thursday.
After pulling up outside the branch, the two passengers got out armed with a sledgehammer and a handgun.
They forced two security guards making a delivery to the bank to open a case containing cash.
The man with the sledgehammer then attacked a cash machine before both escaped with a large amount of cash.
All three men then fled in the getaway car down Commercial Street.
It comes exactly seven weeks after the same bank was raided in an almost identical incident.
On that occasion, on the evening of September 16, two men armed with sledgehammers assaulted a crew delivering cash to the bank.
They also attacked the front of the bank, smashing one of the glass doors, before stealing a large amount of cash and fleeing in a silver BMW bearing false number plates.
A West Yorkshire Police spokesman said the two incidents had not yet been linked but added: “Enquiries are at an early stage. We’re not ruling anything out.”
In October last year heroin addict John Rhind, 35, was jailed for five years for stealing £7,000 in two armed raids on the same bank, when it was called Bradford and Bingley.
Detectives investigating Thursday’s incident have appealed for the public’s help, particularly with tracing the movements of the silver Mondeo.
The spokesman added: “We are particularly keen to speak to two potential witnesses, one of them in a small car, who may have seen the suspects as they recklessly overtook the car on Bethel Street.
“The second witness is believed to be the driver of a vehicle which the suspect vehicle allowed to travel out of Park Street as the incident was taking place.”
One of the robbers was white, about 5ft 10ins tall and slightly built.
He was wearing a dark hooded waterproof jacket, black woollen gloves, combat trousers and spoke with a northern accent.
The second was about the same height and of slim to medium build.
He was wearing a dark coloured hooded top, gloves, blue jeans and white trainers with stripes.
