The suspected terrorist, responsible for the bombing attack on an Israeli tour bus in the Bulgarian Black Sea city of Burgas, had a second ID document, discovered by the investigation in northern Bulgaria.

The news was reported by the Bulgarian Telegraph daily, writing the second ID was fake as well. The first one was a forged US driver's license found near the scene of the blast.

According to Telegraph, the authorities are still furiously searching for the alleged accomplices of the perpetrator, and it is believed that the latter have used fake UK and French passports.

The Interior Ministry has not denied or confirmed the above information.

Remains of the man recovered from the scene of the fatal attack were used to create an image showing his possible appearance as part of an appeal for public assistance in identifying him.

Last week, Bulgaria asked all INTERPOL member countries to make public the computer generated image of the suspected terrorist in a bid to identify the man, which still remains unknown.

At the request of Bulgarian police, INTERPOL issued a Black Notice – used to seek information about unidentified corpses – to each of its 190 member countries in all four official languages (Arabic, English, French and Spanish) and is now also publishing this reconstructed image to engage the public's help in identifying the man.

The July 18 terrorist attack in Bulgaria's Burgas, also known as the Burgas Bus Bombing, killed 5 Israeli tourists and a Bulgarian bus driver at the Sarafovo Airport. The initial lead, purported by Interior Minister, Tsvetan Tsvetanov, was that it has been executed by a suicide bomber, who arrived from abroad.

According to observers and terror experts, this lead is looking less and less reliable and the most viable hypothesis is that the perpetrator has been deluded, used as a mule, and has acted under the influence of illegal drugs.

Israeli media largely back the above, writing that the young man with light complexion and blue eyes had been blown remotely, while standing between two coaches with Israeli tourists. He had been unaware that he was going to die and had the task to put the explosive on one of the buses. The bomb was placed in his backpack.
