The bank themselves may not be interested in getting the police involved but maybe your daughter should. She should report it firstly to make sure it is made aware of (as you say this isn't an isolated case) and secondly to secure her account from it possibly happening again. May I suggest the following;

(The following is extract taken from the above site/page:
Fraud and Scams
If you are a victim of Fraud, often also referred to as ‘scams’, you should make a report.
The National Fraud Reporting Centre Action Fraud is available to report fraud offences on line or by phone.
Local Police should take a formal report of fraud in the following circumstances:
Where the person suspected of committing the crime can be easily identified.
Where the person reporting or the victim is vulnerable.
Where the crime is in progress.
Victims of fraud often believe that they know the person who has defrauded them because of what they have been told by mail, phone or over the internet.
Fraudsters use technology to hide their true whereabouts and identity.
All information that they have provided about themselves may be false.
Action Fraud will accept reports from overseas where money has been lost and there is a clear link to the UK. A report to your local Police in your country should also be made.
Hope this helps.
