Sailendra Nath Roy, 49, a West Bengal Police Home Guard, died while performing a stunt; zip-lining by his ponytail.

Roy was trying to cross the Teesta River, located in Darjeeling, nearly 600 feet in the air on a zip-line which was attached to his shoulder length ponytail.

 It was performed in an effort to break his own Guinness world record of zip lining by a ponytail, this time trying to cover more distance.

He had completed about half the distance when he suddenly stopped. As a crowd looked on in horror, Roy became entangled and could no longer propel himself forward. The stuntman lost his grip and got tangled in the wires. 

The sheer panic from the tangle induced massive cardiac arrest and Roy died at the hospital from a massive heart attack.

He was hanging in the air for 25 minutes fighting for his life. He tried his best to free himself from the tangle.  There was no quick way to get help and after 45 minutes he was brought down from the wire unconscious and lifeless.

Dr. AK Saha, Resident Doctor at the hospital said, "He was brought dead into the emergency ward. He was already dead when he was admitted to the hospital. We have sent his body for post-mortem. The official reports are not yet out, but we believe it is due to a heart attack. He must have had a cardiac arrest."

Roy achieved the Guinness World Record after covering 271 feet on a zip-line while attached by his hair in 2011 in Rajasthan, India. He also used his hair to drag a train on the Darjeeling Himalayan Railway.

The gruesome tragedy took place in front of hundreds of onlookers, most of them children who will not forget the frightening image of a man slowly dying while hanging in the air completely helpless.

Among the onlookers was Roy's brother, whom says he is proud of his bravery.

Watch the video of the deadly stunt but beware...it's pretty upsetting.
