“These are two vulnerable, older gentleman – they could die,” said Stuart Potts, who runs the Saving People Shelter Project.
“If you’re not going to give anyone any kind of alternative accommodation, nobody in their right mind is going to move onto the street, especially with winter coming on.”
Bury Council said it was “obviously concerned if vulnerable people are still in the property”, with a spokesman saying they had asked Mr Potts for the men’s details.
Mr Potts said the local authority had been trying to get hold of all the property owners and landlords, so works to bring the building up to standard could be agreed upon.
The building is a combination of privately-rented and resident-owned flats.
“The council did act to help residents immediately after the fire last year, providing some with temporary accommodation in a hotel and those with higher priority with permanent rehousing,” the council spokesman said.
But ultimately the prohibition notice on the building means “no one should be living there,” he added.
Mr Cook and Mr Henry’s landlords have been contacted for comment.
