SAD-Man behind ALS Ice Bucket Challenge dies after drowning aged 27

The man behind the latest internet craze - The ALS Ice Bucket Challenge - has died after drowning in a diving accident.

Corey Griffin, 27, had helped the campaign become an internet sensation after watching his friend Peter Frates struggle with motor neurone disease.

On Friday night, Mr Griffin had called his father to share his joy over the astonishing amount raised by the social media campaign.

But, tragically, just hours later on Saturday, Mr Griffin died after diving into the ocean from a building on Straight Wharf in Nantucket, Massachusetts.

His father, Robert Griffin, told The Boston Globe: "He was the happiest guy in the world. 

"He called me… and told me he was in paradise."

The ALS Ice Bucket Challenge began in America and has since seen celebrities from across the world soaked with ice cold buckets of water to raise money for the Amyotrophic Lateral Sclerosis (ALS) Association. 

Corey's father said his son was tortured by his Mr Frates' ordeal with the disease and had urged him to come visit his friend during their call.

“He was so happy to be able to help him," Mr Griffin added.

"He cared about everybody else. He will be missed."
