Anti-virus software entrepreneur John McAfee has been found dead in a Barcelona prison cell hours after a Spanish court agreed to extradite him to the US to face tax evasion charges.
The Catalan Justice Department said prison medics tried to resuscitate him, but were not successful.
It said in a statement that “everything indicates” McAfee took his own life.
A controversial figure in the tech world, his company released the first commercial anti-virus software.
McAfee VirusScan helped to spark a multi-billion dollar industry in the computer world, and was eventually sold to technology giant Intel for more than $7.6bn (£4.7bn).
