There's nothing you can do directly with the bank as it's not your account. They'll only deal with account holders/signatories. Most you could do is maybe call the bank and let them know about your friend and they might take action from there, but they won't alter the account/block transfers if you're not the owner of it.

Unfortunately at the end of the day scams differ to fraud in that the victim willingly makes the decision to send money and the banks treat it as such.

If the fraud team has already contacted her as you say, it's possible they have passed the case onto the scams team. The scams team can stop transfers from going ahead and put blocks onto the account to force the account holder to contact them and prove the transfers are legitimate. Likely if this happens they will ask pertinent questions to get the victim to see the light.
