Police on Monday detained Md Dulal, a security guard of Tanvir Iftekhar Dihan’s house, over the death of an O-level student after being raped in capital's Kalabagan area.
According to police, Dulal was on the run since the incident.
Dhaka Metropolitan Police (DMP) Deputy Commissioner (DC) of Ramna division Sajjadur Rahman confirmed the matter to the media.
After detaining, the security guard was taken into the custody of Kalabagan police station for questioning about the incident, he said.
Earlier on January 9, the victim – Anushka Noor Amin – was laid to rest in Kushtia. She was “sexually assaulted” and “killed” on January 7 in the capital’s Kalabagan.
Police received the 17-year-old’s body from a hospital and arrested her “boyfriend” Fardin Iftekhar Dihan and three of his friends from there.
The victim had gone to a friend’s house in Kalabagan for group study, family sources said.
Anushka’s father filed a case against Dihan the same night, accusing him of sexually assaulting and then murdering her.
Dihan, who is alleged to have raped and killed her at his family flat in Kalabagan, gave a confessional statement before a Dhaka court on January 8.
Dhaka Metropolitan Magistrate Mamunur Rashid recorded the statement and sent him to jail pending further hearing, according to an officer of Kalabagan Police Station.
The court fixed Jan 26 for the next hearing.
Meanwhile, doctors performing the autopsy of Anushka found evidence of rape in her body.
After completing the autopsy on January 8, Dr Sohail Mahmud, head of the forensic department at Dhaka Medical College, said she died due to excessive bleeding in her vaginal and anal areas.
Samples were also collected for DNA profiling and to determine whether any anaesthetic drug was administered to Anushka.
Dr Sohail added that the exact cause of death could only be confirmed once the autopsy report is out.
In the meantime, law enforcement released three youths – detained for questioning over the incident.
They were let go as the police did not find their involvement in the incident after a primary investigation, Abul Hasan, assistant commissioner (New Market Zone) of Dhaka Metropolitan Police, said, “However, the police will keep close tabs on them.”
