Arson at 10 pottery terrace

This property 10 pottery terrace is a NCHomes property 4 flats,the gentleman at flat 2 has been moved out after an arson attack at the rear of the building.I had reported that the gates to the yard had fallen down in November last year,unfortuanutly this was not responded to. The condition of the building(pictures) have been seen by NCH,and they sent someone around on the 12th April,he managed to screw a 1 metre square of plywood over the hole at the rear,and kids pushed it through the next day.If its possible to pass these concerns on to NCH as it is a blott on the neighborhood,and not safe for the two tenants living at the property.
