A second body has been found at the scene of Friday's explosion and fire at a Bosley Mill, police have said.
Cheshire Police said investigators made the discovery on Tuesday morning as they searched for two further people who remain unaccounted for. The first body was recovered from the wreckage on Sunday, but is yet to be identified.
In a statement assistant chief constable Guy Hindle said officers continued to work in "very difficult conditions" with "ongoing risks" while they tried to preserve the scene for further investigation.
He said: "It is an extremely complex scene to examine and we've not yet got full access to it. Each agency has a wide range of expertise, and representatives from each are dedicated to the investigation and making the best use of their skills.
"We are making a number of enquiries, but we have to bear in mind that we can't compromise the rescue operation. We are interviewing witnesses and gathering other evidence, all of which will form the investigation."
The find comes as the full extent of the damage at Wood Flour Mills, near Macclesfield, was revealed. The four-storey structure was reduced to rubble.
Fresh images released on Tuesday by Cheshire Fire and Rescue Service have for the first time revealed the extent of the damage.
It has also emerged that there were two previous fires at the site in 2010 and 2012, and there were recent complaints about sawdust and noise, Sky News has reported.
