Bolstering the Delhi police's case against Rahul Mahajan, a forensic report has concluded that the samples of gastric lavage (stomach wash) and vomit stains found on his clothes showed presence of heroin and cocaine.
The report by the Central Forensic Sciences Laboratory, given to the Delhi Police on Friday, said traces of heroin and cocaine were present in the stomach wash and vomit samples of Rahul and his aide Bibek Maitra, police sources told PTI.
But the report did not find any traces of alcohol, they added. Rahul, who was released on bail on Wednesday, had denied taking drugs and alleged there was a "hidden agenda" at work against him.
Sources said while the test report of Rahul showed presence of the two psychotropic substances, the gastric lavage of Maitra showed traces of ethanol also besides metabolites of heroin and cocaine.
The two gastric lavages were part of the five samples handed over to the CFSL on June three by the Delhi Police.
Earlier, CFSL sources said they had carried out mass spectro-photometric test and Thin Layer Chromatographic on the stained clothes of Rahul and Maitra during which it again found stains of the two psychotropic substances.
The Delhi police had handed over an upper garment as well as an under garment of the duo for examination.
A pouch recovered from Maitra's body, which was also handed over to the CFSL by the Delhi Police, has already been confirmed as heroin.
