Two young men from separate households in the same union of Faridganj upazila in Chandpur district, died by suicide within an hour on Friday.
The incidents occurred in Sholla village under Subidpur West Union on Friday evening.
The first incident involved 16-year-old Fahim, son of late Rafiqul Islam and a bakery worker in Dhaka, who ingested poison at his home.
Fahim's sister, Laboni, reported that he had been in a relationship with a local girl. Four days prior, he returned home, insisting on marrying the girl, but the family dissuaded him due to his young age.
In distress, Fahim consumed poison. Despite efforts to save him, doctors at Chandpur General Hospital pronounced him dead.
Shortly after, 18-year-old Abu Osman, from the same area, was found hanging in his room. Abu Osman, son of Abdul Motaleb, had been in a relationship with a girl he met over mobile phone.
Family members revealed that Osman's parents had forbidden him from communicating with her, which they believe drove him to take his own life. Abdul Motaleb shared that his son had recently graduated from Sholla School and College, passing his Higher Secondary Certificate (HSC) exams.
Motaleb explained that he and his wife had gone to a family gathering, leaving Osman at home, only to return and find him hanging from the ceiling with his mother's scarf.
Faridganj Police Station officer-in-charge Hanif Sarkar said that police have sent both bodies to the morgue for autopsy, and two unnatural death cases have been filed.
Legal procedures are ongoing as authorities continue their investigations, he added.
