THE Maharashtra Anti-Corruption Bureau (ACB) probe into the graft case registered against 36 suspended policemen from Nehru Nagar police station is likely to take several months,as voice spectrogram tests are required to match the voices of each of the cops with video footage of a sting operation conducted against them.
The ACB,which is recording the statements of the policemen,are also sending their voice samples,in batches of two or three,to Kalina Forensic Science Laboratory for the voice identification tests.
Voice identification tests need to be conducted to prove that the voices heard in the video footage of the sting operation are those of the policemen under investigation. This cannot be done at one go,as such tests take time. We are getting the tests done in batches of two or three policemen at a time, said a senior ACB official.
The Mumbai Police Crime Branch had to wait for over four months to receive a report on a single voice spectrogram test conducted on Zabiuddin Ansari,an accused in the 26/11 terror attack case who was deported to India from Saudi Arabia in 2012. The Crime Branch had to send two reminders to the FSL,urging it to file its report at the earliest.
ACB officers said Kasim Khan,the whistleblower who carried out the sting operation,has finally given his statement to the investigating officer. The ACB had earlier said two summons sent to Khan had gone unheeded.
However,we are yet to receive the original recording of the sting operation from Khan,as he is unable to produce it. This is crucial to the case as only the original recording and the device on which it was recorded will be admissible in court as primary evidence. The 21 DVDs we were given are only copies of the original recording, said the officer.
The 36 policemen were suspended and a case was registered by ACB after Khan came forward with footage of the policemen accepting bribes to allow renovation of a dilapidated structure in the area. The senior inspector who was in charge of the police station was also suspended but has not been named in the graft case.
