Police in Essex and Suffolk have issued warnings about a sophisticated 'sextortion' email scam.
The scammers first accused their victims of accessing adult websites. They then claimed to have downloaded their personal contacts, accessed their computers and filmed explicit videos on the victims own webcams.
They claimed if the victims didn't pay a Bitcoin ransom they would release the material to their friends and families.
Police say say six people in the two counties have been targeted since July 10.
According to police the emails are different to common phishing emails as they contain a lot of detail and contain an example of a password used by the victim.
Police say anyone receiving a suspicious message should not reply or pay the ransom and should change all their passwords.
