Lakhai (Bengali: লাখাই), is an upazila of Habiganj District in the Division of Sylhet, Bangladesh.[1]

In the village of Madna, the army set fire to the house of Dewan Ali. On 29 October, the Pakistani forces took shelter in the houses of some brokers at night in Muriyauk. Early in the morning, they wanted to go to the house of Shahjahan Chishti, a freedom fighter in Muriyauk. Unable to find Chishti at his house, the forces captured his sixty-year-old father, Abdul Jabbar, and set the house on fire. In the same village, the forces also captured 65-year old Idris Ali, father of Bengali freedom fighter Ilias Kamal. They then proceeded to kidnap the two old men to Lakhai Union. According to some sources, the next day the forces took a speed boat to Bhairab and the old men were shot dead on the way and were never found.[3]
