A leak in Dubai Mall‘s massive aquarium on Thursday led to shoppers being evacuated and boutiques closed around the major attraction, witnesses said.

The perimeter of the aquarium, said to be the largest in the world and which holds a number of different fish including sharks, has been cordoned off and shops around it closed.

“A leak was observed” at one of the points where the panels of the Dubai Aquarium intersect, Dubai Mall said in a statement.

“The problem was immediately contained by the aquarium maintenance team. The leak did not affect the aquarium’s environment or the marine animals in it”.

Dubai Mall, which has a whopping 1,200 stores, is the largest mall in the Middle East. It is located at the foot of Burj Khalifa, the tallest tower in the world.
