Mithu Singh, who has been arrested for allegedly killing an MBBS student at Bandra Bandstand, cleared the narco-analysis test because he was under the influence of alcohol while committing the crime, said the Crime Branch officers. The reports of his narco, lie detector and brain-mapping tests were inconclusive, they added. The officers have also learnt that when the local cops were first looking to conduct his narco test, Singh had denied permission. He, however, agreed later, after researching about it, they said.

The narco test

According to the Crime Branch officers, at the narco test, Singh admitted to meeting the victim at Bandra Bandstand. But, when he was asked what he did to her, he told the same story he had told the investigating officer before, that she disappeared from the location after he left her there. On questions about the method of killing and the location of the body, he said he had no idea, cops said.
