A father who lost his 8-month-old son in the February 22 earthquake says he and his young daughters would probably have died in one of a spate of suspected weekend arson attacks if he hadn't been woken by a neighbour.
The spate of weekend arsons has Christchurch police worried someone could soon lose their life.
The Fire Service was called to seven fires between 12.44am and 1.42am in Aranui early on Saturday morning.
Two of the fires were on Ben Rarere Avenue, three were on Aldershot Street and two were on Portsmouth St.
Detective Sergeant Chris Power said a vacant house was set alight along with two garages, with another fire being lit very close to a house and others in rubbish bins and skips.
