Three people snatched a small shark from a pool at the San Antonio Aquarium and smuggled it out in a baby carriage over the weekend. Leon Valley Police Chief Joseph Salvaggio said officers initially refused to believe that the 911 call that came in Saturday was real. But “they finally convinced me that it was true somebody had walked in and stole a shark out of a aquarium.

Security video released Monday shows the sharknappers strolling through the aquarium’s hallway pushing the baby carriage along on Saturday before they drove off with the 16-inch shark in a red pickup truck. The aquarium said the thieves brought their own net with them to snag the shark from an interactive “touch pool” at the tide pool exhibit while an attendant was assisting other visitors.

They then ducked into a filter room and emptied out a bleach bucket, into which they deposited the shark, the aquarium said. They used the bucket to transfer the shark into the stroller and “hurried up the stairs and out to the parking lot,” it said. The aquarium said managers raced to the parking lot and caught up with the suspects — who denied access to both the vehicle and the stroller. Salvaggio told reporters at the aquarium Monday night that police tracked the vehicle down and found a house close to that vehicle. They were able to recover the shark and get confessions from two of the suspects, he said.
