(Reuters) - Police in Belize want to question U.S. anti-computer virus software pioneer John McAfee in connection with the murder of a neighbor he had been quarrelling with, but they say he remains a person of interest at this time and is not a suspect.

"He is a person of interest at this time," said Marco Vidal, head of Belize's police Gang Suppression Unit. "It goes a bit beyond that, not just being a neighbor."

Police officers were looking for the software engineer, said Miguel Segura, the assistant commissioner of police.

Asked if McAfee was a suspect, he said: "At this point, no. Our job ... is to get all the evidence beyond reasonable doubt that Mr A is the one that killed Mr B."

"He (McAfee) ... can assist the investigation, so there is no arrest warrant for the fellow," added Segura, who heads the Criminal Investigation Branch.
