CHRIS EUBANK JR admitted that Sebastian's death was the most difficult moment in his life.
Seb, who suffered a heart attack last July while admiring the sunset over Dubai's waterway, tragically died.
Seb's wife Salma Abdelati, and their son Raheem (TAG2] survived him.

Although the Eubank family is still grieving the loss of Seb, they are thankful that his legacy will continue through Raheem.

"I have never dealt with anything so difficult in my entire life."
"My brother, whom I was very close to, I just want to thank God that he had a boy just before his death and that he now lives on through his son.
"He was an amazing human being. He will always be remembered.
Eubank Jr., 32, has pledged to treat baby Raheem as his "own" child.
He wrote in an emotional social media message: "Now, your legacy will live through your beautiful newborn boy and I will treat them like my own."
"Watch over us, young lion.
