Abir decides to kill Alina as it becomes difficult to take custody of her. He had found a SIM card on the road and planned to use it to demand ransom from the child’s family, but could not contact them as the SIM card was out of service, the PBI said after the arrest of the first suspect was.
The police, taking the suspect with them, raided different places and recovered Alina’s shoes and the kitchen knife used in the murder. The victim’s father later initiated a murder case with the EPZ police.
The PBI got two days to interrogate Abir on Saturday and raided different places taking the suspect with them. The investigation branch of the police interrogated Abir again on Monday after taking him into custody for seven days. His parents and sister were also arrested that day and taken into police custody for three days.
