A Threads post alleged that its author saw a rat in a ground-floor food premises at Maritime Square, Tsing Yi, at about 11.30pm on October 31. The post said the rat appeared to be in the kitchen or food-storage area.
The photographs were described as showing one rat standing on a paper egg tray, with trays of eggs, cans and metal containers nearby.
The poster later said there were two rats at the same time but managed to photograph only one.
