A shark snatched from the San Antonio Aquarium and wheeled out in a baby stroller is back in its petting tank, and investigators say they've arrested someone who has confessed to the deed.

Surveillance video had shown two men and a woman sneaking the 2-to-3-foot-long gray horn shark from the aquarium in a stroller Saturday afternoon. They got away in a pickup truck, which Salvaggio says was recovered Monday evening.

Investigators in the San Antonio suburb of Leon Valley say the person in custody was charged Monday night. Police Chief Joseph Salvaggio says two others are expected to be charged. No names have been released.
