A Christchurch eye surgeon has denied attempted murder after an alleged home invasion in Lyttelton earlier this month

Ian William Dallison can be named for the first time after interim suppression lapsed at Christchurch District Court.

The 65-year-old was earlier charged with grievous bodily harm after two people were injured in an alleged stabbing.

Police say the people involved were known to each other.

New charges were laid today in court, including attempted murder of a man.

It's also alleged Dallison had six firearms with him - including a semi-automatic pistol, handguns and revolvers.
