A bank employee denied sketching robbery plans which were then used by her boyfriend to carry out a raid at a branch in Leeds, a court has heard.
Rachel Shariar-Namini is alleged to have provided inside information about a Natwest branch where she used to work to help aid the £370,000 robbery.
Leeds Crown Court heard her boyfriend William Wormald, Darren Ashcroft and David Cowie have admitted their parts.
Shariar-Namini, 23, of Victoria Avenue, Rothwell, denies robbery.
It is the Crown's case that she is guilty because she provided inside information.
The court was told the robbery took place at the Natwest branch in Church Street, Hunslet on 9 March.
'Plans a joke'
In police interviews read out to the jury, Shariar-Namini recalled a drunken night where she wrote on the plans, but denied sketching them out.
In the interview she claimed it was her boyfriend who had drawn the plans.
She said that she thought the plans had been thrown in a bin and it was all a joke.
She told police: "My life is my work, that's all I talk about."
The jury was told Wormald and Ashcroft, who were masked, entered the bank and gestured staff away from their desks while one went to a temporary storage area where the money was waiting to be collected by Securicor.
It is alleged Shariar-Namini had "detailed knowledge" of the layout and procedures having previously worked at the Hunslet branch until about a month earlier when she was promoted and moved to Rothwell as manager.
The court was told some months before the robbery she had been introduced to Wormald and they became a couple.
He was not well off, working in a builder's merchants, and she paid for things.
The trial continues.
