The 48-year-old from Doncaster was sentenced on Friday, September 5, 2025, at Sheffield Crown Court. Stefy Bull, a former professional boxer who once fought Amir Khan in 2007, later became a well-known coach and manager. The court heard that he used the secret Encrochat phone system under the name “Yummycub” to buy large amounts of cocaine during March to May 2020.
Boxing coach Stefy Bull’s sentencing at Sheffield Crown Court
During the trial, the jury listened to messages showing Stefy Bull arranging to buy drugs priced around £38,000 a kilo. Prosecutor Sam Ponniah said one message linked “Yummycub” to Stefy Bull’s gym in Denaby Main, and another to his house in Doncaster. A birthday reply of “thank you” in May 2020 also helped police confirm his identity.Stefy Bull denied the charges and suggested that one of his fighters may have used his phone, but he did not name anyone. After a four-day trial in June 2025, the jury gave a unanimous guilty verdict. Judge Peter Hampton told Bulcroft at sentencing: “The reality is you chanced your arm at trial, just as you chanced your arm at offending.”His co-defendant, Benjamin Williams, admitted his part earlier in February 2025. Williams pleaded guilty to conspiracy to supply cocaine, possessing cocaine and cannabis with intent to supply, and possessing criminal property. Because of his early plea, he was given a lighter sentence of about 8½ years. Police also found £84,000 cash, £9,500 worth of cocaine, and cannabis inside a safe at Williams’ home in June 2020. Both men will serve up to 40 percent of their terms in prison.Also Read: “He Is The Only One”: Inside Coco Gauff’s Bond With Boyfriend Jalen Sera After Her US Open Heartbreak Against Naomi Osaka
