Prosecutors in Berlin said Tuesday they have closed their investigation into the spectacular collapse of a huge aquarium last December after an expert report failed to pin down a reason why the tank burst.
The AquaDom aquarium, which stood in a hotel lobby in the center of the German capital, burst in the early hours of Dec. 16, sending 1 million liters (264,000 gallons) of water gushing into the building and the street outside. Two people were slightly injured.
