Two garment workers were killed in separate incidents in the capital's Kadamtali and Demra areas on Friday, while muggers stabbed a fabric trader in Shyampur and stole Tk250,000 off him.
The body of garment worker Md Rana, 35, was found hanging at his Muradpur residence around 4pm, while another garment worker, Md Sabuj, 15, was stabbed to death near Signboard area in the morning.
Fabric trader, Shahidul Islam, 50, was admitted to Dhaka Medical College Hospital (DMCH) with severe injuries.
Police said when informed by local residents, they went to the house and found Rana's body, his hands and legs tied with ropes, hanging from the ceiling.
"He might have been strangled to death after his hands and legs were tied by the killers, who then hanged the body," said Sub-Inspector (SI) Md Shaheen of Kadamtali police station.
Rana, who was from Chandpur district, had been living there with his eight year-old son, Limon. His wife, also a garment worker, lives nearby separately because of a family feud.
Limon told police that some friends of his father's had come to the house around 1am yesterday.
SI Shaheen said: "He (Limon) heard angry words between his father and those people, and they also beat up his father. But Limon could not elaborate further."
In another incident, Sabuj was stabbed by muggers around 7:30am as he was going home after a night shift.
The victim's brother Shafiur Rahman said the criminals stole cash and a mobile phone that were on Sabuj.
"Locals found him lying with stab injuries and took him to a clinic. When we came to know of it, we took him to DMCH where doctors announced him dead at 9am," said Shafiur.
Meanwhile, Shahidul Islam was indiscriminately stabbed by unidentified criminals around 1am near the Lal Mosque in Shyampur, when he was going home to Badda, from Pagla in Narayanganj.
His brother Abdur Rouf said muggers stole Tk250,000 and left his brother lying on the road. He was taken to a local clinic but when his condition deteriorated, Shahidul was shifted to DMCH around 4pm.
Stabbed in the abdomen, Shahidul's condition was said to be critical.
