Parasail operators claim an Australian man who plunged 40 metres (100ft) on a Thai beach caused his own death by unbuckling his harness.
Roongroj Rakcheep, who took Roger John Hussey into the air on his tragic voyage, was charged with recklessly causing death but said it was not his fault.
'He told us that Mr Hussey was nervous and panicked, so he accidentally unbuckled the equipment,' Karon police Lieutenant Suwisit Srirak told local media.
Roger John Hussey (left) has been killed in a horror parasailing incident on popular Kata Beach, in Phuket, on Wednesday. Within moments of being lifted up into the air, he plunged more than 400m to his death in the shallows below (right)
'He added that he tried to tell Mr Hussey to stay calm, but it was too late.'
Deputy Chief Inspector of Karon Police Station, Lieutenant Colonel Suwisit Keereerak, said Mr Roongroj told him Mr Hussey was holding both the clips correctly when he went up.
The septuagenarian then took away both hands and put them in the air - appearing to wave to those below.
But when he put his hands back on the equipment he may have have squeezed the clips, which released him.
The entire horrifying incident was captured on video by Mr Hussey's wife, who was standing on the shore of the packed beach watching her husband, along with dozens of beachgoers

Mr Hussey waved to his Thai wife Boosabong Tongsanga (L), who recorded the horrifying accident on video, as he equipment was checked before the flight
'We are still investigating and will check the real cause again before proceeding,' Lieutenant Colonel Keereerak said.
Mr Roongroj, 38, and boat driver Monthein Jandang, 45, insisted all the equipment was fully functional and in good condition.
The pair also said it was replaced every three months to ensure safety, and maintenance offers who examined it after the accident found nothing broken.
However, the company confessed to operating the boat without the presence of a technician on board, which is illegal.

The two staff who were charged were named as the parasilor Rungroj Rakscheep, 38, and Montien Chandeng, 45, the boat captain
Ms Boosabong said she and her husband watched people parasail for three days to make sure he could handle it, and also denied it might have been suicide.
'My husband wanted to try it because it was a new experience for him. He was in good health and had no problems in his life that would have caused him to do this on purpose,' she said.
However, shocking new footage has emerged of parasail operators stand barefooted on tatty ropes at more than 80 metres in the air at the same beach.
Taken in April at the same location and at about the same height, it showed how staff without any safety equipment dressed in shorts and t-shirts fly up on the rigging.

They then haul themselves up to crouch and stand on the webbing, just inches from metal safety clips attached to a tourist’s harness as they prepare to steer the parasail during landing.
Footage of Mr Hussey's death shows Mr Roongroj performing an identical stunt, flipping up onto the ropes moments before his passenger comes loose and falls.
Mr Hussey was seen chatting to his instructors about the activity, with one telling him to 'start running' when the boat on the water takes off.
But only 15 seconds after taking off, the Perth-based businessman can be seen losing his grip on the parasail with the instructor trying unsuccessfully to grab hold of him.
