Police arrested a couple from Hawalkhali of Satkhira's sadar upazila early Saturday in connection with killing their newborn baby and hiding the body in a septic tank to stage the incident as 'stealing'.
The arrestees are- Sohag Hossain and his wife Fatema.
"Sohag filed a general diary on Friday morning mentioning that his 15-day-old baby boy Sohan went missing on Thursday afternoon," said Asaduzzaman, officer-in-charge of the Sadar Police Station.
"His wife Fatema also claimed that her minor boy was stolen from her lap while sleeping in the afternoon. Later, police started to investigate and visited the spot several times. At one stage of inquiry, they detained Sohag for interrogation who made confession to police," the OC added.
Following his information, police recovered the body from the septic tank of their house 36-hours after the missing report and arrested the couple.
Later, Fatema confessed that she killed her kid following pressure from her husband as the baby was premature and sick.
Legal action would be taken against the couple, the OC said further.
