Two youths, including a rice trader, were beaten to death in separate incidents in the city's Shahbagh and Sutrapur areas on Monday night.
The deceased were identified as Ali Asgar Swapan, 25, owner of Jahan Traders at Babu Bazar, and workshop employee Anwar Hossain, 20, of Dayaganj.
Shahbagh police said they found Ali Asgar lying in an unconscious condition at a bus stop in the evening and rushed him to Dhaka Medical College Hospital (DMCH) where he died at around 8:00pm.
Police, however, could not ascertain the cause of the murder as well as identify the killers.
Swapan's brother Sobhan Bhuiyan told The Daily Star yesterday that he went out of their Sabujbagh residence for Mirpur at around 3:30pm.
Sobhan said since the afternoon, they could not reach Swapan's cellphone which remained still missing.
Morgue sources, however, said he was beaten to death.
In another incident, employee Anwar Hossain was alleged beaten to death by his employer Abid Miah and three other employees on charge of stealing iron from the workshop at Dayaganj.
Anwar's brother Amir Hossain said his brother died after Abid Miah and other employees tortured him mercilessly at around 9:00pm.
