The only person accused of lighting one of Australia's deadly wildfires was a lonely Web-surfer who liked dogs, always said "G'day" to neighbors, and was trying to find love online.

Brendan Sokaluk, 39, who reportedly once served as a volunteer fighter, was named as the suspect police arrested last week.

Authorities are keeping Sokaluk at a secret location to protect him from potential reprisal attacks after a magistrate lifted a ban on publishing his name.
