Ahead of a nail-biting election on Sunday in Moldova, Serbian police arrested two persons suspected of training Moldovan and Romanian citizens to cause chaos on polling day.

Serbian police arrested two persons suspected of organising training in Serbia for Moldovan and Romanian citizens in “providing more effective physical resistance to police officers in case of riots during election day in that country [Moldova], scheduled for September 28″.

One of those arrested, L.P., is suspected of organising training in a hospitality establishment near the western Serbian town of Loznica, and another person, named S.S., allegedly helped him, the Ministry of Interior said on Friday.

The training was reportedly organised from July 16 to September 12 for 150 to 170 Moldovan and Romanian citizens.
