The body of 55‑year‑old Ranjay Baruah was discovered hanging from a ceiling fixture in a washroom at Krishi Bhawan, the Assam Agriculture Department headquarters, Thursday morning.
Baruah had not returned home after leaving the office on Wednesday, and his mobile phone was missing, according to staff.
Staff member Rabin Malakar, who entered the building at 10:20 a.m., reported seeing colleagues discussing the missing employee before finding the body.
Assam Police have opened a murder investigation and are collecting evidence at the scene.
Department spokesperson S. Kalita said the department would cooperate fully and conduct an internal review.
