Wearing nothing except a large smile, a man jumped into the largest exhibit at Ripley's Aquarium of Canada in downtown Toronto late Friday and swam among sharks before security asked him to leave — but it didn't end there. 
 
 One minute-long video posted on YouTube shows the man taking off his clothes and diving into the Dangerous Lagoon, a 2.9-million-litre tank that offers an underwater gallery to dozens of marine animals. 
 
 The naked man can be seen doing the breaststroke on the surface of the water while sand tiger sharks swim within centimetres of his feet. 
 
 Green sawfish, green sea turtles, green moray eels and other species of tropical fish are also housed in the tank, according to the aquarium's website. 
 
 Security at the popular tourist attraction asked the man to leave shortly before 10:30 p.m. ET but he refused, said Jenifferjit Sidhu, a spokesperson for Toronto Police Service. 
 
 Instead, he swam to the edge of the enclosure and emerged from the tank before doing a backward flip into the water, she told CBC Toronto on Monday.

 Visitor Erinn Acland said she heard the "big splash" and thought the trainers were feeding the sharks. As Acland and her boyfriend approached it, she said, they saw a man in the water. 
 
 "The guy seemed totally relaxed and there were sharks like everywhere," she told CBC Toronto. "He appeared to be totally nude and like laughing." 
 
 Acland described the display as unexpected and horrifying. 
 
 "I don't know what would possess someone to do that. It's totally insane to me," she explained. 
 
 "I was scared I was going to witness the death of this guy." 
 
 A video by a visitor who captured the man's aquatic adventure has received more than 5,000 views on YouTube. 
 
 On-site security called police, said Sidhu.

 But before officers arrived, the man got out of the water. 
 
 A video shows him walking past security standing on the edge of the tank, jump the gate and slip into a crowd of onlookers where a woman appears to be holding his clothes. He put them on and left the aquarium at the request of security, Sidhu said. 
 
 No marine animals were harmed during the stunt, she noted, adding the swim was "extremely dangerous." 
 
 "It put the man's safety in jeopardy, the safety of the marine animals and the safety of the staff who tried to get him out of the water," she told CBC Toronto. 
 
 Police haven't been able to locate the man, but they are looking to speak to him. 
 
 He could be facing charges of trespassing, mischief and indecent exposure, said Sidhu. 
 
 The aquarium was hosting a monthly Friday Night Jazz event, which has a cash bar and live music until 11 p.m. 
 
 Police have launched an investigation into the tank incident. CBC Toronto has reached out to the aquarium, but hasn't received a response. ||||| A man who skinny-dipped in the shark tank at Ripley’s Aquarium of Canada is wanted for assaulting a man at Medieval Times earlier in the same night, police say. At around 8 p.m. on Friday, a 34-year-old man was randomly assaulted outside of Medieval Times, near Dufferin St. and Saskatchewan Rd.

 Employees at the venue had apparently asked the suspect to leave for being disruptive, Toronto police Const. Allyson Douglas-Cook told the Star. The suspect later returned and smashed two glass doors, she said. Afterwards, outside the venue, the man allegedly approached the victim who was smoking a cigarette and assaulted him. She said the victim and suspect had no prior contact.

 “The victim was seriously injured enough to be taken to hospital,” Douglas-Cook said, adding that he had black eyes and a broken tooth. The suspect fled the area after the assault. Later that same evening around 10:30 p.m., police said they received a call about a man who dropped his drawers and jumped into a tank full of sharks at Ripley’s Aquarium. “Further investigation revealed the man involved in both incidents was the same person,” Toronto police said in a press release. On Monday night, Douglas-Cook said police were able to identify the man with help from the public as David Weaver, 37, from Nelson, B.C.

 He is wanted for assault causing bodily harm and mischief interfering with property. Security camera footage shows a man entering the aquarium in downtown Toronto shortly after 10 p.m. He bought a ticket before immediately taking off his clothes, climbing over the security barrier and jumping into the water, Ripley’s officials said in a statement.

 “Ripley’s Aquarium of Canada is co-operating with authorities and is willing to press all appropriate charges once the individual has been apprehended,” the statement read. Videos captured by onlookers show the naked man swimming in the tank as sharks dart by in the water beneath him. As he was climbing out of the tank, in front of the security person who was waving him out, he took a backward dive off the rocks and into the water as people in the crowd cheered. The skinny-dipper then hoisted himself out of the tank, hopped over the gate and headed into the crowd where a woman handed him what appears to be clothing. “There were no injuries to the man, animals or patrons,” police said. Employees brought towels to the man and told him to stay on-site until the police arrived, said Derek Marlow, who saw the stunt. “Once he got his clothes back on, he and his girlfriend walked right out of the aquarium despite security staff yelling at him to wait for police and get back in this small holding room they wanted to keep him in,” Marlow told the Star. His friends saw the man at Union Station later, Marlow said. Police described Weaver as 35-40 years old, five-foot-ten and 220 pounds. He has a shaved head, a dark goatee, a tattoo on his lower leg and is missing a front tooth. He was last seen wearing a dark hoodie, dark jeans, a green teal T-shirt, and grey and white shoes. Police say he may be be driving a green Dodge Caravan with the British Columbia license plate number PL120G. Anyone with information is asked to contact police at 416-808-5200 or call Crime Stoppers anonymously at 416-222-TIPS (8477).

– "I was scared I was going to witness the death of this guy": That's what one visitor had to say after a man decided to go skinny dipping with the sharks at Ripley's Aquarium of Canada. The man stripped down and then went over a security barrier and jumped, completely naked, into the Toronto aquarium's largest exhibit Friday night. It's called the "Dangerous Lagoon," and a spokesperson for Toronto Police Service tells the CBC the man's stunt was, in fact, "extremely dangerous" to him, the marine animals in the tank, and the staff that tried to get him out of the water. The aquarium was open late at the time for its Friday Night Jazz program. Security personnel asked the swimmer to exit the water but he instead swam to the edge, got out, then did a backward flip right back in. "The guy seemed totally relaxed and there were sharks like everywhere," the aforementioned witness notes. Eventually, the man did get out, put his clothes back on, and slipped into a crowd of onlookers. Security had called police, but the man was gone by the time they arrived; they are currently investigating the incident. They want to speak to the man, and the police rep says he could face charges including trespassing, mischief, and indecent exposure. The aquarium says it will press charges if the man is found, the Toronto Star reports. (This shark likes the taste of plants more than meat.)
