Serbian media claims Ahmed Almuhamed, 25, was one of the terrorists who allegedly blew himself up at the Bataclan concert hall – leaving 89 people dead.
The Blic newspaper also claims that Almuhamed posed as a refugee when he arrived in Europe via the Greek island of Leros last month, along with another of the bombers.
Two of the terrorists are believed to have been carrying Syrian passports, while another may have had a Egyptian passport.
The only man to have been arrested so far, Omar Ismael Mostefai, was a French citizen.
At least 129 people have died in the attacks, which took place on Friday night across Paris.
At least 89 people were killed when gunmen stormed a performance at the Bataclan concert hall.
A football fan was killed when suicide bombers targeted the Stade de France during an international fixture, while 49 people were killed when gunmen attacked people at a number of restaurants and cafes.
Seven of the terrorists blew themselves up using suicide belts, while an eighth man was shot dead by police.
