Police say a major bitcoin fraud is now under investigation.

It was a man living in the Nord police region (the four northernmost counties) who, after "liking" a page about the cryptocurrency bitcoin online, got a call.

The caller said he worked for a financial company.

The man was convinced to create an account, and began transferring money believing he was buying bitcoin.

Stopped replying

He must then have been able to see for himself how the money increased in value.

He continued to transfer money - but then the counterparty stopped responding.

The man tried to make contact without success, and then realized that he had been tricked.

The police were contacted.

At the time, the man had transferred approximately one million kroner to the suspected fraudsters.

The police want to warn against this type of fraud.

"If an investment seems too good to be true, it probably is - find out the facts and avoid being deceived," the police write on their website.
