An empty building in Ashton-under-Lyne, Greater Manchester, was filmed by an onlooker as it fell like a pack of cards. An engineer on a cherrypicker was trying to make it safe.

Officials made the decision to cordon off the area after it became clear the building was in imminent danger of collapsing - which it suddenly did.
