According to the source, authorities currently analyze the documents regarding the ammunition transport and will continue to examine and collect evidence.
Four containers holding 16 rocket warheads each were stolen Saturday afternoon from a train which was transporting ammunition from Brasov county, central Romania, to Bulgaria.
People close to the matter said Sunday the warheads were produced at a weapon factory in Zarnesti and were exported to Bulgaria. The private ammunition transport was watched over by gendarmes.
According to the sources, the train made three stops on its route to Bulgaria and railway company CFR employees in Giurgiu, close to the Bulgarian border, alerted authorities after they noticed the seal of a car was broken.
The Bulgarian Defense Ministry said Sunday, cited by Novinite.com, the warheads stolen Saturday were for a private Bulgarian company, not for the Bulgarian Army.
