Garda∅ in Dublin have confirmed they are still investigating the circumstances surrounding the death of the Palestinian ambassador, Mr Yousef Allan, in January.
A spokesman for the Garda would not comment further last night, but it is understood that lethal levels of carbon monoxide were found in the body of Mr Allan (47), who was found dead at his home in Dublin's Haddington Road 10 months ago.
A report in Ireland On Sunday suggested the death, which had initially been attributed to a heart attack, may have occurred because the gas supply to his home had been tampered with.
No death certificate has been issued for Mr Allan. Ms Br∅d Doyle, of the General Registry Office, explained that a delay in issuing a death certificate would occur when a person died in an accident, or in violent or mysterious circumstances.
She said that when the Garda was involved in the case the Coroner's Court could not begin its deliberations until the Garda had completed its investigations.
Mr Allan's successor, Mr Ali Halimeh, said he had heard rumours about the circumstances surrounding his predecessor's death when he arrived in the State in July.
"It was brought to my attention through friends but I have not been approached officially by anyone about it. We have not been told anything," he said.
"It is a matter for the Department of Justice, Foreign Affairs and the garda∅ and I would prefer not to intervene in it. I'd prefer they come to a conclusion and contact myself then." He said he would "of course" be concerned if it was found that foul play had been involved in the death of Mr Allan but stressed that he did not feel in danger himself.
"I'm not worried about that. I have never felt threatened in this country. I have always been made welcome." Mr Allan's widow, Ms Jane Allan, who is living in London, is said to be in close contact with senior garda∅.
