Kim Dotcom has a packed day to mark the sixth anniversary of his arrest - getting married and launching new legal proceedings against the New Zealand Government.

Dotcom, who ran the file-sharing site MegaUpload, was arrested on January 20, 2012, for alleged copyright infringement, racketeering and money laundering.

Dozens of police officers and helicopters were involved in the early morning raid of Dotcom's Coatesville home. Since then he has been fighting extradition to the United States from New Zealand.
