The deceased, a BJP Yuva Morcha activist, was found hanging in Ghosh Bagan area of north Kolkata, police said.

A Bharatiya Janata Party (BJP) worker was found hanging inside an abandoned building ‘under mysterious circumstances’, sparking tensions in Kashipur area of north Kolkata in West Bengal Friday morning. Union home minister Amit Shah, who is on a two-day visit to West Bengal, is expected to visit the BJP worker’s residence today afternoon.

According to reports, the BJP has cancelled all celebrations over Shah’s arrival in the city. A senior BJP leader said Shah was upset after hearing the news and told them to ‘cancel his grand welcome at the Netaji Subhas Chandra Bose Airport’ in Kolkata.

The deceased was identified as Arjun Chowrasia, a BJP Yuva Morcha activist. He was found hanging in Ghosh Bagan area of north Kolkata, police said, as quoted by news agency PTI. It is not clear as of yet if it is a case of suicide or a politically-driven murder.

Heavy security has been deployed in the area in anticipation of clashes between the ruling Trinamool Congress and the BJP. Local media has reported protests by BJP workers and supporters near the site of the incident.

The BJP has alleged that he was murdered by the ruling TMC, which has denied the charge. “He was an efficient party worker. We found him dead this morning,” said state BJP spokesperson Samik Bhattacharya.

Refuting the allegations, TMC MP Santanu Sen said, “The allegations against us are baseless. Let the police investigate the matter”.

Police said an investigation into the incident has been launched.
