The British cyber-security researcher who was praised for stalling the worldwide WannaCry cyber-attack has been arrested in Las Vegas.
Marcus Hutchins, 23, has been charged for involvement with Kronos - a separate piece of malware used to steal banking logins from victims' computers.
Fellow cyber-security researchers have expressed surprise at the indictment.
"It looks like the US justice system has made a huge mistake," said fellow researcher Kevin Beaumont on Twitter.
Mr Hutchins was arrested while at an airport, according to a colleague who wished to remain anonymous.
"We tried to visit him at [the detention centre], but he was moved before visiting hours," they told the BBC.
"We've not had any contact with him for 18 hours now."
