The convict was identified as Deshbandhu Biswas, 50, owner of Shantilata Clinic and Diagnostic Centre.
Mohammad Kamrul Faruk, officer-in-charge of Kotalipara Police Station, said Bithi Halder, wife of Bidhan Halder of Pirarbari village, was admitted to the clinic on November 9 following her labour pain, and condition deteriorated after the clinic owner conducted the operation.
Bithi was later admitted to Khulna Medical College Hospital.
Following a written complaint submitted by the victim's family, a mobile court, led by ASM Mahfuzur Rahman, who is also the upazila nirbahi officer, conducted a drive at the clinic and found that the operation was conducted without any doctor and nurse.
The court then sentenced the clinic owner to three months' jail.
