A 16-inch-long horn shark has been safely returned Monday night to the San Antonio Aquarium after it was stolen over the weekend, CBS affiliate KENS-TV reports. Surveillance video from the facility showed three suspects scoping the facility out for more than an hour Saturday afternoon. Then one of them snatched a female horn shark, named Miss Helen, from its tide pool exhibit, according to the Leon Valley Police Department, and wrapped it in a blanket. Then one of the male suspect then put the animal in a stroller to disguise it as a baby for a clean getaway in a SUV in the parking lot.

Later, a man allegedly posted a picture online of a horn shark that included a caption that read “selling a horn shark, perfect for the next shark week. Alive and well just took out of tank for a quick pic.”

He was reportedly selling the sea creature for $300. It was unclear if the man who posted the image was linked to the incident at the aquarium. The post has since been deleted.

KENS-TV says that two people have confessed to stealing the shark.

Earlier, the aquarium posted about the incident on its Facebook page — including images of the three alleged suspects in hopes that it would spur interest and information from the public.
