The site by wannabe also had a lot of photos, including a couple towards the end inside the same section as that in the photo of the man knocking the wall down.
Its taken me a while to figure it out, but the photo by JAE appears to be looking into the two buildings from the main street with the coopers lounge on the right, hence that triple skin wall is holding up the rest of the building.
The rather light weigth trusses are holding up the roof which existed between the coopers brick building and the next building along the PAve building.
It would definitely seem as if it was that wall which collapsed, unsurprisingly as most of it had been demolished.
Utterly criminal behavior.
