Police investigating Friday’s fire at a disused building in Crewe have arrested a 12-year-old boy on suspicion of arson with intent to endanger life.
Some residents have been unable to return to their homes on Saturday morning.
Crewe Lifestyle Centre is being used as a rest centre for those residents.
Meanwhile, firefighters continue to work at the scene of the fire which started at a former printworks on Catherine Street.
There are no reports of any injuries, according to Cheshire Police.
Superintendent Claire Jesson said: “I’d like thank residents for their patience while emergency services continue to work tirelessly at the scene.
“We understand people will want to get back into their properties as soon as they can, and we are all working hard to ensure that it is safe for you to do so.
“Agencies will continue to work with displaced residents to keep them updated as to when they can return.
“While our colleagues from Cheshire Fire and Rescue Service tackle the fire, we continue to urge residents in the nearby area to stay indoors with their windows and doors closed at this time.”
