A medical center in Bulgaria's Black Sea city of Varna has suffered from a bomb explosion in the small hours Sunday.
The bomb went off around 4 am, damaging the entrance door, breaking the ground level windows, and destroying expensive equipment.
The medical center was blasted with a grenade, thrown intentionally at the place where the Doppler equipment was.
Varna is a residence of the main pharmacy monopolist Mareshki, whose daily earnings in selling drugs are about $ 10 millions (which is quite a big number for such small market).
Varna is also known as the only city in Bulgaria which is "owned" by the mafia and that same person Mareshki takes part of it.
One hypothesis is that this is a sign, send from the pharmacy industry.
Second one - insurance fraud.
