Robert Loeffel is a spokesman for the police in the South region and he warns of this type of call when someone wants to demand someone's bank details.

Never disclose their information

- Never, regardless of what they claim, should never disclose any information about their accounts cards or codes. You have to hang up the phone and then you call the police. You should never be intimidated by whatever they say, says Robert Loeffel.

The pattern of action is not new to the police and it is described as a national problem.
