The anti-virus millionaire John McAfee, who is on the run from police in Belize in connection with the murder of his neighbour, has been arrested in Guatemala.

McAfee was detained on suspicion of entering the country illegally, according to the interior minister Mauricio Lopez Bonilla.

The founder of McAfee software, which he sold in 1994 before retiring in 2008, has been on the run since 11 November, when his neighbour Gregory Faull was discovered shot dead in his home on the island of Ambergris Caye.

McAfee is wanted "as a person of interest" in the case, police in Belize say, but insist he is not a prime suspect.

Authorities attempted to have McAfee expelled to Belize on Thursday, but McAfee's lawyer, Telésforo Guerra, is challenging that move. McAfee said he attempted to apply for political asylum, arguing that he would be in danger if he was forced to return to Belize.

According to McAfee, "the urgency [has] eased a bit" after a judge issued a stay order until a higher judge could be called to review his case.

There is no international arrest warrant for McAfee

Since going on the run, McAfee has communicated with the world via an occasionally erratic blog, in which he has described his elaborate methods of disguise, protested his innocent and claimed he is being set-up by the police and former employees.

He crossed into Guatemala with his girlfriend and was eventually detained at the Intercontinental hotel in Guatemala City.

In one of his latest blog posts he reiterated that he was not responsible for Gregory Faull's killing. He said:

To the family of Gregory Faul: I had nothing to do with his death. I have lost five close family members in my 67 years and I know your suffering.

To the Belizean Police: I will answer any questions that you may have over the phone. If I am indeed merely wanted for questioning, this should suffice.

To my supporters: I have posted many short posts over the past three days during the setup and execution of my exit from Belize. The information was intended for my pursuers. I regret that it may have confused or alarmed many of you. I hope you will consider the circumstances and forgive me.

To my freinds: I will be in touch soon. I have not slept for 24 hours. I am in non-stop meetings and strategizing our next steps. I will call and email you soon. I love you all.
