Guatemalan police have arrested US software developer John McAfee for illegally entering the country and said it would seek to expel him to Belize, which he fled after being sought for questioning.
McAfee, who had been in hiding for three weeks, crossed into Guatemala with his 20-year-old girlfriend to evade authorities who want to quiz him as "a person of interest" over the murder of Gregory Faull.
"He entered the country illegally and we are going to seek his expulsion for this crime," Interior Minister Mauricio Lopez Bonilla said after McAfee was detained at the Intercontinental hotel in Guatemala City.
One of Silicon Valley's first entrepreneurs to build an internet fortune, the 67-year-old made millions of dollars through the antivirus software that now carries his name.
His behaviour has been increasingly erratic in recent years but there is no international arrest warrant for him. Police in Belize say he is not a prime suspect.
McAfee's lawyer Telesforo Guerra was seeking an injunction to have him released, with the American denying any involvement in the murder, insisting he has been framed.
