Logan Paul has attempted to salvage his reputation by uploading a seven-minute YouTube clip dedicated to suicide prevention, after worldwide condemnation for a video showing the dead body of a man who had killed himself.

The 22-year-old, who is understood to have made a fortune from his YouTube career, pledged a $1million donation to suicide prevention charities in the clip.

Mr Paul was dropped from YouTube's Preferred programme after he was blasted by high profile names and media outlets for trivialising mental health, and the trauma inflicted upon families who have lost loved ones through suicide.

Despite more than 500,000 people signing a petition to delete Mr Paul's YouTube, his account has remained online and his brother, Jake Paul who is also a YouTube star, recently claimed that he was certain he would make a comeback.

"I have been given an opportunity to make a difference in the world," Mr Paul says in the latest video which was published on Wednesday evening.
