The Gujarat police said on Sunday that a ‘tantrik’,who was arrested earlier this month for allegedly plotting to kill a man in Ahmedabad, passed away in custody.
They, however, claimed the accused admitted to killing 12 people by administering a toxic chemical.
The Sarkhej police arrested Navalsinh Chavda around 1 am on December 3 when he was on his way to commit the crime, after his business partner tipped the police off.
The police secured Chavda's remand till 3 pm on December 10 for further probe into his occult practices and possible involvement in human sacrifices.
However, the accused fell ill on Sunday morning and died while being moved to a hospital.
The accused, he added, had confessed to killing 12 people using a chemical called sodium nitrite.
