The incident started on Wednesday morning when the man, Nuruzzaman Kajal, went to a local madrasa around 8am and said that his younger son, ‘Safayat’, was electrocuted.
He requested the local mosque authority to announce the news of his son's death through loudspeaker and to send someone to his house for the Quran recitation.
Meanwhile, rumours spread around the area that Kajal had murdered his son.
Law-enforcing agencies surrounded his two-storey house on being informed. The news also led many journalists and local people to gather around his house.
A member of the Detective Branch suffered injuries in his hand as Kajal attacked the detective who tried to enter the house.
Police finally managed to convince him that Safayat’s funeral prayers should be held as it was time for Zuhr prayers.
When Kajal came downstairs, the policemen caught him and Fire Service workers took Surayat away.
Later the body of Safayat was recovered from the house and sent to Dhaka Medical College morgue for post-mortem examination.
“There is no wound on the boy’s body. We can’t say how he died before we get the post-mortem test report. We are not accusing his father or anyone else of the death now,” Maruf Hossain, a deputy commissioner of Dhaka Metropolitan Police, told reporters.
His brother Nurul Huda Ujjal claimed Kajal was addicted to drugs.
Kajal have been been living in the house with his two sons after his wife left some days ago following an assault by her husband, Ujjal added.
