Crack on the wall
It is uncertain when the crack first formed.
When Mothership visited the mall on Aug. 25, the crack appeared to start at the very top of the building's facade, and extended downwards for several metres.
Several people were also spotted standing in an outdoor area on the second floor of the mall, inspecting the crack.
The open area directly below the front-facing facade of the mall was cordoned off for safety reasons.
As such, visitors were observed having to take a longer path around the cordoned-off area to enter the mall.
