Police are yet to trace the newborn stolen from Dhaka Medical College Hospital a week ago.
Several law enforcement agencies have been working round the clock to nab the culprits and recover the stolen twin boy, Sub-inspector Ferdous Alam of Shahbagh Police Station told this newspaper.
The police early yesterday raided different places in Tongi and Ashulia on the outskirts of the capital to arrest a woman who is suspected to have stolen the baby.
The victim's mother Ranu identified the woman from a CCTV footage. Posing as an attendant of an imaginary patient, the woman on August 21 had offered services to Ranu as she was struggling to nurse the twins.
The woman disappeared with one of the infants around 7:30am. The DMCH authorities on the same day filed a case with Shahbagh Police Station in this connection.
"We've collected the cell phone number of the suspect from the hospital authorities. The woman is frequently changing her location in Tongi, Ashulia and Mirpur," mentioned Ferdous, who is also the investigating officer in the case.
Following media reports that the theft had occurred at the DMCH when the CCTV cameras there were not in use, hospital staff were seen setting the cameras in proper positions yesterday.
Meanwhile, tipped off by local people, police yesterday rounded up a woman from Goalghat area in the capital's Wari and recovered a baby boy from her, said Tapan Chandra Saha, officer-in-charge of Wari Police Station.
During interrogation, the detainee confessed to police about buying the baby from his mother for Tk 20,000 on August 18.
A woman from Companiganj in the area was also brought into the police station after the detainee claimed that she had bought the baby from the former to adopt him. The woman admitted selling the baby to the detainee for Tk 20,000.
