Sammy the Whale shark

Speaking of seafood, the multibillion dollar Atlantis hotel in Dubai has somehow acquired a whale shark in their gigantic aquarium. It's a girl named Sammy (!?). The hotel claims that a local fisher who caught it in the wild thought it was sick and proceeded to release it in the hotel's fish tank. Former employees, on the other hand, claim the hotel management always wanted a whale shark as an attraction. The whale shark is listed as vulnerable (that's not good), so it is against international law to keep them in captivity. Atlantis hotel says they were planning the release it as soon as possible.

Seriously, which story sounds more plausible?
