The official website of the New Zealand Police posted a notification informing citizens that a threatening email sent by a group calling themselves Syrian Electronic Army hackers is being investigated.

The email threatens life and safety of receiver's relatives, demanding to pay $1,500 in bitcoin.

"Police are aware some email recipients may feel very vulnerable after receiving an email of this nature. Anyone who does feel at risk should contact their nearest Police station to express their concern.

Other recipients may not feel as threatened but may still wish to assist with the investigation in order to prevent it from spreading further. We would like anyone who has received the SEA email to send it to This email address is being protected from spambots. You need JavaScript enabled to view it. (link sends e-mail) in order to help us with our investigation," reads the official website.

A few days ago bitcoin was prohibited in Taiwan after a Hong Kong tycoon had been kidnapped, his abductors wishing to be paid in bitcoin digital currency.
