Sixteen people were hurt when a 33-ton aquarium containing sharks, other fish and turtles exploded at a shopping centre in the Chinese city of Shanghai.
CCTV pictures captured the moment the giant tank burst, sending glass and fish flying into the crowd.
A man who was taking pictures of the aquarium when it broke was swept away by water.
Shoppers, store assistants and security staff suffered cuts and bruises as they were hit by pieces of 15cm-thick acrylic glass.
Three lemon sharks and dozens of small fishes and turtles were killed, according to reports.
Police have begun an investigation after the tank burst without warning.
"I was just walking by and heard the explosion of this water tank. I heard a bang, then water flushed out," said an unnamed passer-by.
"A cosmetics counter collapsed. The shop assistant was pulled out by other people," said another unidentified witness.
A safety expert said: "According to experts' preliminary investigation, the main cause of the incident is that the material used to make the aquarium ruptured under low temperatures after long-time use."
The Orient shopping centre said it had no plans to rebuild the aquarium which had become a popular attraction since it was installed two years ago.
