The Wellington scammer

The Dom Post reports:

A phone scammer targeted Wellington residents last night, the second incident in two weeks.

Police said they received about 40 phone calls last night from people who had a phone call from a bogus Microsoft employee.

Last night’s incident follows about 50 calls to Wellington, Hutt Valley and Kapiti residents last Wednesday and Thursday, reporting a similar experience.

The caller claims to work for Microsoft and offers assistance to help get rid of a virus by disclosing computer passwords.

Police warn anyone who receives a call of this nature to hang up immediately.

If the calls are being made from within New Zealand, surely the Police can easily ascertain the phone line they are being made from, and take action?
