Private TV station Channel 24 aired the 103-second conversation that, according to it, took place two days after the seven men were abducted.
The station said absconding Nur Hossain, Narayanganj City Ward-4 Councillor, made the call from his Airtel phone to Osman’s Grameenphone around 9:30pm on April 29.
It said Nur Hossain was in the Dhanmondi Road No.4 in Dhaka during the call.
Ward-2 Councillor and Panel Mayor Nazrul Islam, his four aides, and senior local lawyer Chandan Kumar Sarkar and his car’s driver were abducted on Apr 27 in Narayanganj.
The bodies of the seven were retrieved from the Shitalakhyya River at Bandar Upazila several days later.
The slain councillor’s family accused Nur Hossain, locally known to be Nazrul's rival, of being the mastermind, who paid the Rapid Action Battalion (RAB) to carry out the killings.
