UNDATED (CNN) -- French authorities have opened an investigation into the death of former Palestinian leader Yasser Arafat.
A prosecution official says the inquiry comes after last month's discovery of high levels of a radioactive substance on some of Arafat's personal belongings.
Palestinian Authority President Mahmoud Abbas subsequently approved the exhumation of Arafat's body.
Arafat died in 2004 at the age of 75.
He suffered a brain hemorrhage and slipped into a coma at a Paris military hospital.
Rumors of poisoning circulated at the time, but Palestinian officials denied them.
