A 17-year-old boy accused of being the mastermind behind the Twitter hack on July 15 has pleaded not guilty to all charges brought against him by U.S. authorities.
Graham Ivan Clark has pleaded not guilty to all 30 counts against him by U.S. authorities at an appearance at Hillsborough County Courthouse, Florida, on Tuesday, the Tampa Bay Times reported.
Clark told Circuit Court Judge Christopher Nash in Tampa that he was not guilty of the 30 felony counts of fraud prosecutors have leveled against him, according to court records.
A 19-year-old British man and a 22-year-old man in Orlando, Florida, have also been charged under U.S. federal law with aiding the attack, the Justice Department said.
Clark netted at least $100,000 from the scheme by using the celebrity accounts, state officials reported.
