Miss Helen, a 16-inch-long horn shark in the San Antonio Aquarium in Texas, lives in a tank where visitors are encouraged to touch the animals. Three people took the encouragement too far this past weekend, lifting the shark out of the tank and plopping her into a baby stroller, the police said.

The trio of sharknappers — Ocean’s Three? — can be seen on surveillance video using their own net to capture Miss Helen on Saturday, removing her from the 76-degree water after staking out the pool for more than an hour, the aquarium said in a statement. She was placed into 52-degree water to make her voyage — a shock to the system that her handlers feared would quickly kill her.

But Miss Helen, who’s less than a year old, proved her resilience, from her snout to her caudal fin. And the thieves, if bad at covering their tracks, turned out to be good at taking care of sharks.

If aquarium employees are correct in their suspicions, the thieves were also skilled at reconnaissance. An official said she recognized one of them from a month earlier, when he said he worked for the facility’s salt supplier and got an all-access tour.
