The Bulgarian Prosecutor's Office is already investigating the murder of a border policeman on the Bulgarian-Turkish border. "I do not rule out Bulgarian investigators going to Turkey to participate in the investigation together with their Turkish colleagues," Deputy Prosecutor General Borislav Sarafov said. If the perpetrators were found on Turkish territory, we would demand that they be handed over to the Bulgarian authorities, Sarafov said.

He spoke from Lukovit, where he attended a joint operation with the Swiss prosecutor's office against a human trafficking group. The 6 men arrested are accused of forcing people into begging and prostitution, leaving them to survive under the bridges of Geneva.
