RDX not used,says forensic report

Another senior lab official,on the condition of anonymity,said,Tests of all the six samples have revealed there were no traces of RDX,which is most commonly used as a booster charge in explosive devices. Ammonium nitrate was used,mixed with a kind of oil which is most probably fuel oil or furnace oil. Prima facie,the IEDs have not exploded as the booster charge like RDX or TNT was not used. The lab tests cannot confirm whether humid air or old ammonium nitrate caused the failure.

Senior ATS officials refused to comment on the report. Some of the officers,who are part of the probe,said the report had not come. The sources from the forensic sciences lab confirmed report was handed over to ACP Samad Shaikh,who is the investigating officer of the case.

The samples were earlier sent to the Institute of IED Management of Central Reserved Police Force in Talegaon.
