A man from Sussex has been jailed for a year for hacking into Facebook.
Gareth Crosskey targeted the account of a US citizen, prompting the breach to be reported to the FBI.
The 21-year-old, from Avon Close in Lancing, admitted computer misuse offences and was sentenced at Southwark Crown Court.
The Metropolitan Police's e-crime unit launched an investigation after he hacked into the account on January 12 last year, also gaining access to the victim's private email.
The Met got involved after the FBI traced the culprit to the UK and Crosskey was arrested at his home on July 14 last year.
A Met spokesman said: "Today's result should act as a deterrent to any individuals thinking of participating in this type of criminal activity.
"By taking swift action, police central e-crime unit officers were able to quickly detain Crosskey, thereby preventing further disruption to the victim."
