Anti-virus software creator John McAfee, who is wanted in the United States for tax evasion, has been arrested at Barcelona airport, police said Tuesday.

Officers detained the 75-year-old on Saturday as he was about to board a flight to Istanbul and he was being held at a jail near Barcelona awaiting extradition to the United States, a Spanish police source told AFP.

His arrest comes a day after US prosecutors released an indictment against McAfee for allegedly failing to report income made from promoting crypto-currencies, making speaking engagements and selling the rights to his life story for a TV documentary.
