Witnesses have today told how horrified passers-by battled to save a man found on fire at Mote Park in Maidstone.
One man desperately tried to fight the flames as two women grabbed jugs of water from a cafe after the man was found alight yesterday afternoon.
The man, believed to be in his 30s, suffered "extremely serious" burns in the horrific ordeal at about 4.30pm.

"We realised someone was on fire so we both ran over there and back to the cafe to grab jugs of water..." - witness Teisha Maytum
Today witnesses Teisha Maytum and Debbie King, who both work at the Cafe at the Park, told how they were among the first at the scene.
Teisha said: "We suddenly saw a fire light, arms waving, and shouting. We realised someone was on fire so we both ran over there and back to the cafe to grab jugs of water.
"There was a man with him trying to fight the flames. By the time we got the jugs back to him he had managed to put it out."
A spokesman for South East Coast Ambulance Service, which sent three vehicles to the scene, said he was in an "extremely serious condition".
Kent Fire and Rescue Service said two crews were also sent to the scene.
It is not yet clear how the man came to be on fire, but a Kent Police spokesman said the incident is not being treated as suspicious.
