Two people have been arrested for the murder of the missing 18-year-old girl from the town of Pernik, near Bulgaria's capital, police said.

Miroslava Nikolova's dead body was found by the police in the suburbs of the town about 11 am on Thursday after two months of active search, which involved the information systems of Schengen and Interpol.

The teenager disappeared on November 7, 2011 and has been missing ever since. On the fatal day the girl went to her regular taekwondo training and never went back home. Friends said she was in good spirits while in the hall and there were no signs of the tragedy that unfolded later on.

A week ago Miroslava's sister Eleanora told bTV channel that the two had one telephone conversation. Miroslava managed to tell her sister that she was kidnapped and policemen were involved in the crime. The kidnappers however never called to set their conditions.

Authorities suspected the girl may have been trafficked aboard as a white slave. Some assumed that she may have fallen in love with someone who is part of a scheme for human trafficking and voluntarily fled the country.

Many locals were inclined to believe that the missing girl ran away from home, a speculation her sister has dismissed as "ridiculous".

Miroslava left her home without documents or money.
