A 43-year old man Subhabrato Majumdar has been arrested in Kolkata, India after it was discovered that he allegedly kept his mother’s corpse in a deep freezer for three years so that he can continue collecting her pension, using her thumb impression.

According to Times of India, Kolkata police found the woman, Bina Majumdar, was a government employee and had retired from Food Corporation of India (FCI).

A police chief Nilanjan Biswas said, “Bina Mazumdar’s body was stored in a refrigerator since 2015. Why her body was stored for three years is being investigated.”

“Subhabrata Majumdar used a debit card to withdraw cash from the pension account of his mother. We are investigating why the bank kept the pension account alive for the past three years without life certificates,” the police chief said, according to Hindustan Times.

Subhabrato, a leather supply businessman was receiving his mother’s Rs 50,000 a month pension with his 90-year old father Gopal Chandra Majumdar, also aware of the incident. Gopal, a law graduate, retired as a deputy manager from the vigilance wing of the Food Corporation of India and started his private practice afterwards but quit in 2013.

According to Times of India, Subhabrata said he kept his mother’s corpse because he believed she could be brought back to life. His dad said he “just went along” with him.

According to the police, Subhabrato, also forged a living certificate which was also discovered by police officers during the raid.
