Sri Lanka's unity government, led by President Maithripala Sirisena and Prime Minister Ranil Wickremesinghe, have vowed to curb corruption and arrest high-profile officials who were involved in financial fraud during the previous government.
Several cases against ministers in the former government have been lodged with the FCID and the island's Bribery and Corruption Commission.
Former ministers named in corruption scandals have denied any wrongdoing and blamed the government for carrying out a witch-hunt.
