A chilling video has been leaked from a computer in a New South Wales police station showing a surfer being attacked by a large shark.
The eight-second video appears to have been filmed on a handheld device inside the police station and shows the attack on a computer screen.
The footage shows a figure in a wetsuit desperately trying to paddle his surfboard away from a large dorsal fin and tail in the ocean before being pulled underwater.
The identity of the person attacked in the video is unknown and it is unclear whether he or she survived the attack.
The video began circulating online after rumours emerged that it showed the moment rising surfer Kai McKenzie survived a shark attack at North Shore Beach in Port Macquarie on Tuesday.
His leg later washed up on the beach and surgeons tried to reattach it as quickly as possible.
But the leaked footage doesn’t seem to fit the description of that attack.
NSW Ambulance worker Kirrin Mowbray told reporters Mr McKenzie managed to fight off the shark before being swept back to shore by a wave.
Although the clip is short, it does not show the surfer resisting, nor do it show waves coming up behind him as the shark attacks.
The video was filmed from a screen that appears to be in a NSW police station and shows a surfer paddling out before a huge dorsal fin and tail appear in the water and drag them underwater.
Ms Mowbray also said there were no witnesses to the attack.
“The only one who saw the shark was the young man himself,” she said.
In the leaked video, a poster can be seen above the computer screen with the text “respect, pride, trust” next to blue and white squares, which matches the New South Wales Police logo.
The same slogan and logo can be found on NSW Police merchandise, including lanyards and drink cups.
In front of the desktop screen where the video was playing, a used lunch box was visible.
New South Wales police confirm they are investigating how the video was leaked and posted online.
“New South Wales Police are aware of a video circulating online and have launched an investigation into how the video became public,” a spokesperson told Daily Mail Australia.
‘New South Wales Police will not tolerate this type of behaviour and will take appropriate action pending the outcome of the investigation.’
The video was shared online as the attack on Kai McKenzie, 23 (pictured), who suffered serious leg injuries at North Shore Beach in Port Macquarie, was broadcast around 11am on Tuesday.
He survived and was rushed to Newcastle’s John Hunter Hospital. Details of the leaked video do not appear to match the description of Mr McKenzie’s attack
The leak occurred days after Mr. McKenzie’s restaurant was attacked by a shark.
A bystander, an off-duty police officer walking his dog on the beach, saw the bloodied Mr. McKenzie emerge from the surf around 11 a.m.
He used his dog’s leash as a tourniquet to stop the bleeding from the injured areas.
Police and ambulance arrived on the scene a short time later and Mr McKenzie was taken to Port Macquarie Base Hospital in a critical but stable condition.
His distraught loved ones rushed to his sickbed and admitted that Mr McKenzie faces a “long road to recovery” regardless of whether the limb can be reattached.
Mr. McKenzie’s nNeighbor Lauren Mac confirmed the 23-year-old had undergone surgery, but would not reveal details about the nature of the operation.
“This is all the family wants released at this time,” she said.
“Kai is currently in John Hunter Hospital where he has undergone surgery and is in a stable condition,” she wrote.
“His mother and father told me it would be a long road to recovery, no matter what the outcome.”

It is believed Mr McKenzie (pictured) arrived at the remote beach with a friend after taking a ferry
a GoFundMe Ms. Mac’s campaign has so far raised more than $130,000 for the young surfer.
He had only recently returned to the water after breaking his neck.
“So happy to be surfing again after breaking my neck,” McKenzie posted on Instagram in January.
He is described as a ‘legendary guy’ and an experienced surfer, sponsored by famous brands.
In the past 20 years, there have been five fatal shark attacks on surfers in NSW. Fewer attacks have been recorded without a fatal outcome.
