Sky News reporter Jason Farrell has been investigating the darker side to the virtual world Second Life - and found an area called "Wonderland" that is being used by child abusers.

Farrell created his own character in the multiplayer online virtual world to carry out his investigation over a number of months.

"Wonderland is a virtual children's playground where paedophiles cruise and kids are solicited," said Farrell.

"At first site it looks like a real-life playground.
