A shark named Helen's weekend adventure is now over, after the animal was smuggled out of the San Antonio Aquarium in a baby stroller on Saturday. Police tracked the shark down at the home of the main suspect in the heist. Both are now in captivity.

Video footage of the bizarre heist fed intense public curiosity – and led to solid tips from the public on the animal's likely whereabouts. Aquarium officials welcomed the shark back on Monday night.

"Ms Helen (our horn shark) is in quarantine right now resting. She is doing good so far, and we are hopeful she will recover fully from the shock, and return to her home she is used to," the San Antonio Aquarium said via its Facebook page.

If you're picturing the shark tucked into a damp blanky, wearing a bonnet as it was wheeled past security guards, the truth of the matter isn't quite that evocative — but it's nearly as unlikely.

Working as a team, the thieves carried out their wet work in plain view of the public and surveillance cameras on Saturday. One man used a net to remove the young horn shark from its large pool exhibit. Another man then followed him to a side room, where they put the 16-inch shark in a bucket and covered it with a towel, according to the aquarium's general manager, Jen Spellman.

Walking back toward the exhibit, a man then put the shark, inside its bucket, into the lower portion of a baby stroller.

In what looks to have been a coordinated move, a surveillance video shows a woman carrying a toddler or infant away from the stroller, walking nonchalantly as the two men take the stroller – now dripping water and holding a shark – to a staircase.

The group went out the front door and rushed to a truck – but they were confronted there by aquarium staff, who had been notified by an employee who noticed their suspicious behavior. Police were also called. In the face of questions from the staff members, a suspect drove off in the truck. He seemingly abandoned the woman and other man who are in the video.

The two men and the woman had spent an hour in the area of the tide pool exhibit, apparently waiting for their chance to nab the shark, the aquarium said.

Describing the heist to the media, Spellman said the bucket had originally contained a 5 percent bleach solution, leading aquarium officials to worry for the shark's health. Most of that fluid was dumped into the aquarium's water system — creating a separate crisis that its employees worked to counter. Staff members were able to prevent serious damage, the aquarium says.

Police say the main suspect in the case seems to have known how to care for the shark, and that he may have intended to keep it with other animals in his home aquarium.

"He had had one of these in the past," Leon Valley Police Chief Joseph Salvaggio said, according to local KSAT TV News. "I think the animal had died sometime in the past. Obviously he likes those types of animals."

The suspect had an extensive aquarium habitat in his garage, the chief said, adding, "He had a lot of different marine animals in the home."

The aquarium is in Leon Valley, a suburb northwest of downtown San Antonio. After tracing the getaway truck, police obtained a search warrant to look for the shark.

Early Tuesday, an aquarium representative said that its founder, Ammon Covino, was grateful to news outlets for spreading the video, saying the intense public interest had helped to recover the shark.

The aquarium's assistant husbandry director, Jamie Shank, accompanied police on the trip to the suspect's house, where she removed the horn shark from a large tank to identify and inspect it.

"I am so, so happy that we got her back, and she's healthy. She appears very healthy," Shank told journalists after returning to the aquarium Monday night. "I was devastated when I found out that it happened. And now that we actually have her here, I'm overjoyed."

"I cannot believe what she's been through. She's a little fighter, she's a survivor — I'm very proud of her," Shank said of the shark, as Ms. Helen moved around in a tub of clean water at her feet.
