Three of the passengers were later admitted to Government M G M Hospital as they did not yet regain consciousness, while the rest four were still feeling drowsy, the sources said.
The seven passengers were found unconscious at Tatanagar station under the Chakradharpur division of Jharkhand and were reported to have boarded the train from Delhi.
The four, who were yet to recover fully, told GRP that they were offered “rabri” (a delicacy) by some unidentified men who befriended them but they fell unconscious soon after consuming the sweet.
However, strangely no belongings of the passengers were found to be lost and the articles were now in GRP custody, the sources said.
