The Austrian national Zlatko Novakovic who died in an explosion in Vienna on Sunday was a respected town councilor and owner of a shipping company.

Novakovic and the second victim of the blow up car, 57-year-old Waldemar W. were good friends, according to their acquaintances, reports BGNES.

The mystery remains of why and how the hand grenade held by the German exploded inside the Bulgarian-registered vehicle.

The police have also found 12 brand new 10 liter gas tanks in the trunk of the car.

Novakovic was an activist in the local branch of the Austrian Social Democratic Party. He was a good friend of the former Mayor of Salzburg Gabi Burgstaller who was involved in a huge affair for misuse of funds.

Novakovic owned a freight company and trucks which he leased to transport service companies. The owner of the unfortunate Bulgarian-registered BMW Georgi Stankov, was an employee of Novakovic and had leased him the vehicle.

Currently, the police are working on three versions. The first version is that Waldemar W. is the author of the attack, and he failed to get out of the car in time.

The second hypothesis is that Zlatko Novakovic has stood in the way of a criminal organization and was assassinated. It is also possible that both victims were involved in illegal activities.
