Guinea-Bissau's attorney general, tasked with investigating the murders of the tiny west African country's president and army head, said Tuesday he had received death threats.
Luis Manuel Cabral said in a radio interview he had received numerous telephone threats and could no longer sleep at home.
"I have recently been receiving a lot of anonymous calls threatening me with death. I don't know who is making these calls," he said on Radio Bombolon.
"Moreover, I have not spent the night at my house for several days," Cabral added.
He is heading a commission charged with shedding light on the March killings of president Joao Bernardo Vieira and the murder of the army chief, General Batista Tagme Na Waie.
The former head of state was killed in apparent revenge for the murder in a bomb attack of the army chief, which came only hours earlier.
The murder of the president triggered an election in the unstable west African country.
Cabral added: "I am not saying members of the armed forces are threatening me, as they are also interested in keeping the situation calm."
Anyone could get his contact information and make the calls, he said.
As well as probing the two murders, Cabral's investigation encompasses what the army claimed was an attempted coup on June 5.
Two politicians were killed by troops after being accused by the military of being behind the plot.
Cabral, former head of a Guinea-Bissau human rights group, said in July last year that he was receiving death threats on a daily basis in a bid to stop him investigating the country's cocaine trade.
