BOSTON (CBS) — The family of Pete Frates, the man who inspired the Ice Bucket Challenge five years ago, wants everyone to know that he is ‘resting comfortably’ at Massachusetts General Hospital–and that a Monday morning report that he had passed away is false.

Journalist Mike Barnicle tweeted Monday morning that Frates had died. His tweet, which has since been deleted, was retweeted over 1,000 times.

Frates himself responded later in the morning with a video of himself in a hospital bed, while Pearl Jam’s “Alive” played in the background.

Barnicle has since issued a correction and said he is “deeply sorry.”

On Sunday, the Frates family said Pete was back in the hospital and “battling this beast ALS like a Superhero,” and asked the public to keep him in their prayers.
