John MsAfee, the fugitive software tycoon wanted for questioning inBelize over the murder of his American neighbour, arrived in Miami on Wednesday night.

Fellow passengers aboard his flight from Guatemala City, where the eccentric 67-year-old was released this morning after a week of detainment, said they were prevented from disembarking while he was taken away.

Airport spokesman Greg Chin said that federal agents greeted McAfee at the door of the plane and helped him through immigration and customs formalities.

A short time later, a posting on McAfee's website announced that he was at a hotel in Miami's upscale South Beach neighborhood.

Investigators in Belize want to talk to McAfee as "a person of interest" in the murder of Florida builder Gregory Faull, his neighbour on the island of Ambergris Caye, last month. Faull, who had quarrelled with McAfee over his "vicious dogs" was found shot in the head, although McAfee has strongly denied any involvement in blog posts during a month on the run.

Guatemalan authorities arrested him and his 20-year-old girlfriend Samantha Vanegas at a hotel in the capital city last week and he spent a week in a detention center before a judge ruled he was in the country illegally and ordered his immediate deportation.
