Halifax Regional Police are reminding people to use caution when giving out personal information.
They say a woman got an email from someone claiming to be a sergeant in the United States military, with an attached photo of a person in uniform.
The email said a diplomat would be delivering a parcel with money or a cheque, and it asked the receiver to confirm a home address.
Police say once scammers get the address, a parcel arrives containing a cheque or cash that is not legitimate.
The receiver is asked to deposit the money in their bank account, and send some of it back to the sender.
Police say calls or emails asking for money, banking information, Social Insurance Numbers, or dates of birth could lead to identity theft.
