Protesters have put up tents in Chisinau, the Moldovan capital, demanding a probe into the disappearance of up to $1.5 billion from three Moldovan banks last year.

Organizers from non-governmental groups erected about 40 small tents Monday in a main square, a day after tens of thousands joined a demonstration calling on the government, the central bank governor, the general prosecutor and others to resign.

The state-owned Savings Bank, the Social Bank and Unibank, where the money disappeared before the November 2014 parliamentary elections, were put under the National Bank of Moldova's administration in December, and the losses were covered by state reserves

An unpublished parliamentary report said some of the money was transferred to Russian banks. The three banks are owned by Moldovan and Russian investors.
