One week after the fire, on 25 January, a meeting was held at the Moonshot Club in New Cross, attended by more than one thousand people. The meeting concluded with a march to the scene of the fire and a demonstration there, which blocked New Cross Road for several hours. The New Cross Massacre Action Committee (NCMAC) was set up, chaired by John La Rose, and organised weekly meetings in New Cross, which saw increasing participation as the police investigation announced that there was no evidence of arson and that the fire was believed to be accidental.
