The father of the 12-year-old boy Sashko who disappeared a week ago has announced a cash reward for finding his son. The father does not rule out the police version that the child was kidnapped, but he did not receive any threats before his son's disappearance. According to him, Sashko knew perfectly well how to find his way home, which confirms the kidnapping hypothesis.

Alexander Tsvetanov is worried that time is passing and there is no trace of his child. A massive search operation in the area has been held. In addition to police, gendarmerie forces, the Bulgarian Red Cross and rescue teams, thousands of volunteers also help. The boy disappeared while walking in the area of Golo Bardo mountain.
