Obaidul Khan confessed to stabbing 14-year-old school student Suraiya Akhter Risha, claiming he was driven by his obsession with her, police said on Thursday.
He said he was alone when he attacked Risha, a Class VIII student at Willes Little Flower School and College in the capital's Kakrail area on August 24, said HM Azimul Haque, additional deputy commissioner of Ramna Division, Dhaka Metropolitan Police.
“During primary investigation, he said he was obsessed with Risha. He also said he did not have any accomplice when he attacked her,” the police official told the Dhaka Tribune. “We are now looking for the murder weapon and working to gather more information.”
Obaidul was placed on remand for six days by a Dhaka court on Thursday in a case filed by Risha's mother Tania Hossain.
Dhaka Metropolitan Magistrate Delwar Hossain issued the order after Ramna Model police station OC Md Ali Hossain, who is investigating the case, produced Obaidul before the court and sought a 10-day remand for interrogation.
In the remand petition, the investigation officer said Obaidul needed to be placed on remand in order to find the motive behind the attack and whether anyone else was involved in the attack.
“We need to interrogate him to find the knife he used to stab the victim as well.”
The investigation officer also requested the court to convert the case from an “attempt to murder” to a “murder” case, which was granted.
Risha’s parents were present at the court during the case proceedings .
There was no defence counsel to petition for Obaidul's bail or remand rejection plea.
Risha's family was represented by Fahmida Akhter Rinky from Bangladesh National Women Lawyers' Association.
Risha was stabbed by Obaidul when she was returning home from school after exam on August 24. She was severely wounded when she was admitted at Dhaka Medical College Hospital and succumbed to her injuries on August 28.
Tania Hossain, the victim's mother, filed the case on the same day with Ramna Model police station under the Women and Children Repression Prevention Act 2000, accusing Obaidul as her daughter's attacker.
Tania claimed that Obaidul was a tailor and a cutting master at Baishakhi Ladies' Tailor in Eastern Mollika shopping mall, in Dhaka's Elephant Road area. A few months ago, Risha went to his shop and placed an order for some clothes, for which she had given her phone number to Obaidul.
Since then, he had been harassing her by phone calls. As she did not respond to her advances, he attacked and stabbed her.
Obaidul was on the run until he was spotted by a local at Domra upazila in Nilphamari on early Wednesday morning, who informed police. A combined team of police and Rapid Action Battalion then arrested him and brought to Dhaka in the afternoon.
Police also arrested Obaidul’s sister Khadiza Begum, 36, and her husband Khadimul Islam, 46, Niratongi village in Birganj, Dinajpur on Tuesday.
Fellow students of Risha at Willes Little Flower School and College have been staging protests demanding justice for Risha after she died. The took to the streets again yesterday demanding capital punishment of her murderer and speedy trial.
