A grieving sister battered a live cobra to death with rocks then burned its corpse after the snake killed her brother in the bathroom.

Jay-ar Bungay, 27, was using the outdoor toilet when he was bit on the leg by the venomous serpent in the town of Paniqui in Tarlac province, the Philippines, on January 7.

He screamed and staggered back to his house before being rushed to a hospital but died on the way as the cobra's potent venom surged through his body.

Shocking footage shows local wildlife handlers catching the serpent before heartbroken sister Erica Canlas screamed as she pounded it to death with rocks.

She says in the video while attacking the reptile: 'F*** you! My brother hadn't done anything to you! F*** you!'

The snake was later burned and disposed of in the woods. However, the incident has raised awareness of the need to anti-venom to be readily available in remote villages, with snakes responsible for an estimated 150,000 deaths annual.

Speaking after, Erica added: 'My brother didn't even last an hour. We had to borrow a car from another village to rush him to the hospital, which was also in another town.

'On the way there, he was conscious but he told us he was getting dizzy and weak. My heart broke when I saw him shaking violently. He died when we arrived at the hospital.'

Jay-ar was buried on January 12. However, the grieving family had to call snake wranglers as the killer cobra was still lurking on their property.

The specialists arrived at the residence on January 13 and began breaking the home's concrete floor where the snake was believed to be sleeping.

They found the cobra slithering under iron sheets near the side of the house where chickens were being kept. It was caught 'in a weakened state' and placed inside a sack.

Snake catcher Rex Mallari said the cobra may have emerged from the nearby field and was attracted to the well near the family's house.

Despite the snake catchers' warnings not to harm the cobra, Jay-ar's grieving family flew into a rage and started bashing the reptile with stones and a metal stool.

Footage shows the emotional female relative repeatedly beating the captive snake as other villagers were heard telling her to calm down.

The family later burned the snake's mangled corpse.

The Tarlac Provincial Environment and Natural Resources Office (PENRO) said it is generally prohibited to kill wildlife, including cobras, under the Wildlife Resources Conservation and Protection Act of 2001.

Dominador De Guzman, Head of Conservation and Development of Tarlac PENRO, said: 'In case of emergencies or if your life is in danger, of course you can protect yourself and kill the threatening animal. There is a provision in the law.

'However, if a snake is found, it is better to surrender it to authorities than to kill it.'
