Tunda was taken to his ancestral home in Bazaar Khurd area in Pilkhuwa yesterday by Delhi Police's special team.
Lalit Mohan, incharge of Delhi police's special cell, said Tunda was brought to Pilkhuwa to get information about potassium dealers who are suspected of having business links with the terrorists.
"Thorough questioning of all those involved in potassium trade will soon be undertaken and whoever is found involved in illegal activities will be dealt seriously," Mohan said.
During interrogation, Tunda had told Delhi Police that he sourced potassium to make bombs from local traders in Pilkhuwa which is famed for its cloth printing industry.
