The 22-year-old, from East Leake, Loughborough, was taken to the Queen’s Medical Centre after what police believe was a disturbance.
He sadly died in hospital.
Mr Griffin’s mother, Zoe Cooke, said: “Byron’s death has absolutely devastated my family. He is my only son and leaves behind three sisters aged 10, 11 and 27 who will never, ever get over this.
“Byron was loved by so many – to the point that one of his old teachers came to see me to pay his condolences despite him leaving school years ago.
“Byron was my absolute heartbeat and our lives will never be the same again - the pain is absolutely unbearable. We are all devastated beyond belief and I wouldn’t wish this on any parent.
“My boy will never hold or kiss me again and I will never come to terms with that.”
