Silchar: A 40-year-old man, Hanif Khan, was found hanging from a tree near his residence at Kashipur (Part-II), in Cachar district on Monday.
Kashipur falls under Udharbond constituency, around 18km from here.
This is the first case of suicide in Assam allegedly related to the first draft of the National Register of Citizens (NRC).
Hanif was a driver by profession and stayed at a rented house with his wife and three children. He originally hailed from Pailapool, around 30km from here.
According to local residents, Hanif committed suicide after not finding his name in the first draft of the NRC published at midnight.
Hanif's wife Raksa Khan told The Telegraph on Monday that her husband had been worried over the NRC issue and always wondered what would happen if their names were not included in the NRC.
Raksa, who works at a photostat shop in the village, said her husband recently feared going outside and immediately returned home if he saw any police vehicle in the vicinity.
She said Hanif had been missing since 7pm on Sunday.
Raksa first saw the body around 6.50am. Police officials reached the spot around 8.30am and sent the body to Silchar Medical College and Hospital for post-mortem.
Sources said a group of unidentified people had told Hanif (after he did not find his name in the draft NRC) that the police would arrest him and his family and they would be deported to Bangladesh.
Cachar SP Rakesh Roushan confirmed that it was a case of suicide.
