Shahjahan Bhuiya, who hanged some of Bangladesh’s highest-profile death row inmates in exchange for reductions in his own robbery and murder sentences, then briefly became a TikTok star after his release from prison, died on Monday in Dhaka.

Bhuiya died at a hospital in Dhaka, the police said on Tuesday, adding that the cause was unconfirmed. Abul Kashem, his landlord, said in an interview that he had driven Bhuiya to the hospital on Sunday after he complained of chest pains.

Last year, Bhuiya told the local news media that he was 74. But according to Bhuiya’s national identity card, provided by Kashem, he was 66 at the time of his death.

Bhuiya was sentenced to 42 years in prison for robbery and murder in 1991, local news media said. But he was able to shave a decade off the sentence because of good behaviour and in exchange for hanging fellow inmates. He was granted early release last year.

In a memoir that he published after his release, What the Life of a Hangman Was Like, Bhuiya wrote that he had put 60 inmates to death. Prison officials have said that the correct figure was 26.
