Lagos, Nigeria (CNN)Joseph Blankson had always been a strong swimmer so when the boat he was in had an accident and capsized, he didn't think twice about jumping in the water to help rescue those who had fallen overboard.
Nigerian man dies after rescuing 13 people in boat accident
Singlehandedly, Blankson managed to pull 13 people out of the river. The father of two eventually became exhausted as he went in and out of the river, rescuing one person after the other.
While trying to save the 14th person, Blankson tragically drowned.
A spokesman for the Rivers State police, Nnamdi Omoni confirmed to CNN that the accident was caused when the passenger boat, carrying 24 people, crashed into an object.
Omoni also confirmed that Blankson, 36, was the only casualty. As he was selflessly saving lives, others in the vicinity - including other boat drivers - stepped in to help rescue the remaining 10 people.
Blankson was known as a selfless and loving man to the people in his life but now, he will always be remembered as a real-life superhero.
His wife, Mercy, paid tribute to her husband: "He was a loving and caring man, a very good father to our kids. He put people first, before himself. He was selfless."
Mercy said Blankson, who lives in Port Harcourt, southern Nigeria, had gone to his village and had boarded the boat with his sisters, who were among the survivors of the accident.
"I was at home waiting for him to come back from work because he works on Saturdays. From work, he went to the village, and when I called him at 2 pm, his phone was switched off."
