Another arson attack has been made on the Christchurch "House of Horrors".
The bodies of Tisha Lowry, 28, and Rebecca Sarah Somerville, 35, were found underneath the semi-detached house in Wainoni Road early last month.
Mrs Somerville's husband Jason, 33, has been charged with murdering both women.
A suspicious blaze razed most of the property several weeks ago and another fire last night was quickly put out by firefighters.
