After ten hours of an intensive interrogation police on Friday morning arrested Dr Rajamanthandan, the CID officer who was heading the SIT set up to probe the NBBUSS vandalism at a local AASU office.
The senior IPS officer was arrested charging him with sabotaging the crucial probe by making public the crucial information on the role of Soobodh Biswas, a charge he has been denying.
The CID SSP allegedly has been trying to help Biswas by providing some inputs to a party or individual who favours Biswas, the main culprit behind the Silapothar clash.
Another allegation against him was an RTI reply where he made public the progress on the probe and acting on these allegation he was suspended on Wednesday to be interrogated. On Thursday again he was interrogated for nearly ten hours which was followed by the arrest.
