Sonali Chakraborty, the wife of former West Bengal chief secretary, Alapan Bandyopadhyay, has received a letter containing a death threat against her husband.
“Your husband will be killed. Nobody can save the life of your husband,” read the letter, which was obtained on Tuesday evening.
A complaint has been registered with Kolkata Police, and they are searching for the subject. So far, no arrest has been made.
Bandyopadhyay was embroiled in a tussle between the federal government and the Mamata Banerjee-led state government in May.
He also applied to have the federal government shift his case from the Central Administrative Tribunal (CAT) Bench in the state capital Kolkata (formerly Calcutta) to the principal bench of the CAT in the country's capital city, Delhi.
The central government brought an action against Bandyopadhyay for not being present to receive Prime Minister Narendra Modi during the official visit to Kalaikunda air base, West Bengal, on 28 May to review Cyclone Yaas.
