This is the tragic last post of a British base jumper - showing him gliding through the air in a photo put out on the same day that he plunged to his death from a Thailand tower block.

Nathy Odinson, 33, from Huntingdon, Cambridgeshire, illegally climbed to the top of the 29th floor of an apartment building in the coastal resort of Pattaya on Saturday night before unwittingly leaping to his death.

Horrifying footage shows the self-professed 'adrenaline junkie' counting down 'three, two, one, see ya' before leaping into the night sky - only to go into a terrifying death spiral with the small parachute flailing through the air.

In a final image posted on the tattooed daredevil's Instagram yesterday, Mr Odinson can be seen angled forwards with his arms pointed out behind him as he whips through the air in a green helmet.

Wearing vans for the audacious stunt, he skims a dusty floor as he is suspended beneath a green parachute.

Staff at the Lumpini Ville Naklua condo checked CCTV and saw that Mr. Odinson and a friend had parked outside and then waited for a time when it was quiet before sneaking into the building.

They then headed onto the roof of the building, with Mr Odison clambering over a small concrete wall on the roof of the building to reach the edge.

The security guard said that he had jumped from the building several times before, which posed a risk for pedestrians walking below.

He added: 'They were making video content for social media. They had done this before and they knew it was not allowed.'

Police and paramedics arrived at the scene shortly after 7:30 pm local time. However, Mr Odinson could not be saved.

Police Lieutenant Kamolporn Nadee, Deputy Inspector of Investigations at the Bang Lamung district police station, said there were no initial signs that Mr Odinson had been attacked.

The policeman said: 'The parachute that the deceased used to jump malfunctioned and was not centered as expected. He was in a terrible state when we arrived.

'The friend who recorded the video of him jumping was questioned and the video was examined as evidence.

'Forensics officers are investigating the case further. They are examining the parachute.'

Mr Odinson was a regular daredevil and had performed skydives and base jumps around the world. He ran a 'sky photography' company and took customers on private skydives.

Police have informed the British Embassy in Bangkok, which is contacting Mr Odinson's relatives in the United Kingdom.
