One of Moldova's leading political parties had some cleaning up to do on Sunday after their headquarters was doused with gallons of human excrement.

The national office of the Liberal Democratic Party (PLDM) in the Moldovan capitol, Chisinau, was sprayed with three tons of raw sewage by protesters during the evening.

According to local news outlet Unimedia, a driver and a passenger in the vehicle that dumped the raw sewage have been identified and are currently under investigation "for hooliganism." No clear motive for their action has been revealed.

The country's ruling coalition, which includes PLDM, has been the focus of protesters who have taken to the streets of the capital in recent weeks. Protests began in Moldova on Sept. 6 when tens of thousands staged demonstrations, demanding a probe into $1.5 billion that went missing from three Moldovan banks before 2014 November parliamentary elections.

Since then, protesters have erected tents in a pedestrian square and staged weekend protests.

Hundreds of pro-Russian protesters blocked the main street in the Moldovan capital during the morning rush hour on Monday demanding the resignation of the government.

Some 400 protesters led by the leader of the pro-Moscow Our Party, Renato Usatii, parked dozens of cars on the Stephen the Great boulevard before dawn Monday, bringing traffic to a halt. The protest ended after more than two hours following discussions with police and city authorities. The government has promised to investigate the missing money.
