Grenfell Tower residents raised concerns about fire safety months before the fatal disaster but their fears were ignored and they were treated as 'sub class citizens', an inquiry has heard. Lee Chapman, the secretary of the Grenfell leaseholders' association, said he had raised concerns about bare gas pipes being run through the stairwell of the building - the only fire escape - during upgrade works in spring 2017. However he was repeatedly refused an independent fire assessment of the building by the Kensington and Chelsea Tenant Management Organisation (KCTMO). Mr Chapman told the inquiry: 'I feel that the way that these concerns were handled is a good reflection of the culture within the TMO and the attitude that it had towards Grenfell Tower residents at the time.
