A New Zealand paramedic was at the heart of the Bangkok bombings overnight, and was helping those wounded at the scene shortly after the blast.
But, as Marko Cunningham was helping treat the wounded and clear bodies following the Thai capital terrorist attack, he may have helped save dozens more lives with what he found outside the Erawan Shrine.
"The shredding of people, the blast, the broke limbs, bones, skin, clothes were just ripped off, people just had no clothes on, charred, it was really nasty."
Mr Cunningham, who has lived in Bangkok for 15-years, said he noticed a plastic bag hanging on a tree nearby as he tended to the wounded.
"I immediately went over to an army officer and told him. He came over and had a look, and then he started to clear everyone out. They thought the same as me that it was a bomb. and it was a bomb. and they managed to diffuse it."
One scene from the bombing, he said, will haunt him for years to come.
"There was a guy about 25-years-old, alive, and he was laying next to his girlfriend holding her hand and he was like mute, he couldn't talk ... he was just looking at us blankly and kept looking at his girlfriend," he said.
"We put him on the board to move him and he started to try to talk, looking at his girlfriend, shaking her hand ... she was dead, that was really, I haven't seen anything like that in ... forever."
Mr Cunningham was also one of the first English speaking rescuers to help aid efforts after the 2004 Boxing Day tsunami.
He also helped during a 2010 bombing in Bangkok, which killed three people.
The Ministry of Foreign Affairs and Trade said there was no information to suggest any Kiwis had been killed or injured in the most recent bombing.
