Moldova's general prosecutor has called for lifting the immunity of a leader of the ruling pro-European coalition so he can be probed on suspicion of involvement in a bank fraud of up to $1.5 billion.

Prosecutor Corneliu Gurin told lawmakers Thursday he wanted to lift the immunity of former Prime Minister Vlad Filat, leader of the Liberal Democratic Party, to investigate the money that went missing from three banks ahead of November 2014 parliamentary election.

Gurin claims Filat had taken bribes of $260 million from a businessman and had indirectly given him control of one of the banks. Filat has denied wrongdoing. Parliament will vote later whether to lift his immunity.

Some 2,000 people gathered outside Parliament on Thursday — the latest protests about the missing money.
