Sadik Bin Sajjad, an 18-year old, reportedly took his own life on Monday, leaving only two sentences as an explanation for the act.
"I can't take it anymore. You guys stay well," read the suicide note found in his room, where Sadik had shot himself with his father's firearm.
According to his family, Sadik was believed to be suffering from intense mental pressure about his upcoming Higher Secondary Certificate examination.
Sadik's father, Sajjadur Rahman, who is also the deputy commissioner for the Ramna division of the Dhaka Metropolitan Police (DMP), said: "We spoke last night. I never thought that it would be the last conversation between us."
The incident took place early in the morning in their Azimpur Government Colony residence, when all of Sadik's family members were still asleep, said Md Saiful Islam, DMP assistant commissioner of New Market Zone.
"The night before committing suicide, he also left some childhood pictures and the password of his personal computer in a note with his father," Saiful added.
Sadik was a student at the Dhaka City College.
Family members said Sadik had been alone at home on Sunday afternoon. They suspect he might have taken his father's pistol from his personal drawer during that time.
Sadik was found lying dead on his bed, Lalbagh police station Officer-in-Charge Ashraful Islam told The Business Standard.
Another police source also said that there might be a clue in his personal computer regarding his involvement in playing violent games.
Dhaka Medical College's Forensic Department Professor, Dr Sohel Mahmud, said that Sadik may have pointed the gun directly at the left side of his head and then shot himself.
"We found the bullet lodged beneath the skin of the right side of his head," he said, adding that this assured that he committed suicide.
Sadik's namaz-e-janaza was held at Rajarbagh Police Lines ground around 3pm on Monday. He is expected to be laid to rest at his hometown in Kaliganj upazila, Jhenaidah tonight.
