He is in Britain after being released on bail and awaiting extradition to Sweden to face rape allegations.
His personal life has always been intriguing, clandestine and above all invoked curiosity. Right now, investigations reveal a very different picture of the man at a time before he shot to fame.
An investigation by Daily Mail throws new light on his formative teenage years. The WikiLeaks founder is reportedly have had an affair with a 16-year-old girl when he was 18 and fathered a boy who is now 20 years old.
In the late Eighties, when he was living in a tiny bungalow in Dandenong Ranges, east of Melbourne along with his mother and stepbrother, he developed his eternal love with the computer. "He didn't go out much at all. He spent almost all his time in there with his Commodore computer. He rarely came out of the bedroom," said his former neighbour.
A year after, Assange developed this adulterous relationship with the 16 year old and moved to a cottage. Following this, the girl became pregnant. Their son Daniel was born when Assange's girlfriend was 17.
Assange's passion for computer suffered no setback even at this time and over the years he became a successful hacker and would spend hours on his computer daily, learning to hack into other computers as the web began to spread around the world.
It was during a police raid in the couple's house in Melbourne that he was charged with a number of offences relating to computer hacking. His girlfriend fled with their baby following this turn of events.
He and his ex-girlfriend spent nine years battling for custody of their son, which ended with a 1999 agreement. Today, Daniel is 20 and is working for a software design company in Australia. Pictures identified as him on the Internet show he has a strong resemblance to his father.
