Police’s Ramna division Assistant Commissioner Shibli Noman made the announcement yesterday while talking to agitating students of Willes Little Flower school and College.
The students were protesting in front of the school, blocking the Kakrail intersection demanding the arrest of Risha’s killer.
Students from nearby Notre Dame College, Viqarunnisa Noon School and College, Siddheswari School and College and other institutions also joined them.
Education Minister Nurul Islam Nahid visited Willes Little Flower School and College and assured students of justice for the murder.
Police and eyewitnesses said students had blocked the road in front of the school and Kakrail intersection area for about two hours from 12:30pm, demanding the killer be given exemplary punishment. The agitation threw the traffic movement in the area into a total disarray.
Around 1:30pm, AC Shibli Noman went there and talked to the students. He assured them the murderer would be caught and asked them to return to class.
“We have got all information about the accused Obaydul. He will be arrested in the next 48 hours,” he said.
Later around 2:30pm, the protest coordinator Muntasir Mahmud postponed the programme till Tuesday 12am.
In the meantime, they want to see the killer arrested. They will hit the streets again on Tuesday and vowed to continue agitation until the killer is arrested, he added.
He also urged students all over the country to observe a human chain event on August 31 at their respective educational institutions for Risha.
The Ganajagaran Mancha has expressed solidarity with the protesters and joined their programme.
The school authorities organised a mourning for Risha in the morning. The education minister and the victim’s family were present, as well as students and teachers.
Minister Nahid urged the public to help nab the suspected killer, whose picture has been circulated in the media.
Speaking at the mourning rally, the victim’s father demanded justice for his daughter before breaking down in tears.
Nahid said he had spoken to the home minister who promised swift steps to bring the killer to book.
Risha’s mother Tania Hossain says she suspects that one Obaidul Khan, a cutting master at Baishakhi Ladies Tailors in Elephant Road’s Eastern Moillika Shopping Mall, stabbed her daughter for refusing his advances.
A murder case was filed with the Ramna police station.
