Dhaka: Bangladesh filed a case against Rizal Commercial Banking Corporation (RCBC) of the Philippines' over the heist of $81 million from Bangladesh Bank's account with the Federal Reserve Bank of New York, reports the UNB.

The case was filed with a New York bank accusing RCBC, casinos and others involved in the heist, Abu Hena Mohammed Raji Hasan, head of Bangladesh Finance Intelligence Unit (BIFU) of the Bangladesh Bank said.

He said there will be a press briefing here on Sunday over the filing of the case.

International robbers stole $101 million from the Bangladesh Bank account with the Federal Reserve Bank through fraudulent instructions against their target of about $1 billion in February 2016.

Although, some $20 million was recovered from a Sri Lankan bank, $81 million, which landed in Manila-based RCBC, could not be recovered.

Most of the money transferred to the Philippines went to four personal accounts, held by individuals.

The Federal Reserve Bank blocked the remaining 30 transactions, amounting to $850 million, due to suspicions raised by a misspelled instruction.

Bangladesh has so far recovered around $18 million of the $81 million transferred to the Philippines. It was later suspected that Dridex malware was used for the attack.
