Rapid Action Battalion (Rab) in a drive arrested parents of prime accused Mizanur Rahman of the murder case of Savar schoolgirl Nila Roy, on Thursday night.
Jamir Uddin, company commander of Rab-4 (CPC-2), said based on a tip-off, around 8:15pm, a Rab-4 team raided a house at Manikganj's Charigram village and arrested the two.
The arrestees -- Abdur Rahman (60) and Nazmunnahar Shadika (50) -- are accused in the murder case filed by the victim's father, and they went into hiding after the murder, he added.
They were handed over to Savar Model Police Station, said Jamir, adding that they are looking for Mizan and others involved with the incident.
Contacted, Saiful Islam, inspector (investigation) of Savar Model Police Station, told The Daily Star that the arrestees were sent to a Dhaka court, and police sought seven-day remand. The court granted two days.
On Wednesday, police arrested Selim Palowan (28), an associate of Mizan, for his alleged involvement.
On Sunday around 7pm, when Nila, a 10th-grader of Aced School, was going to a hospital with her elder brother Alok, they were intercepted by Mizan, who threatened Alok and asked him to leave because he wanted to talk to Nila alone. Mizan then forced Nila into an abandoned house, where he stabbed and left her. Upon hearing her cries, locals rescued and rushed her to Enam Medical College Hospital, where doctors declared her dead.
Speaking to locals, The Daily Star came to know that Mizan was a member of "Shakil and Sakib" gang. Members of the gang are infamous for extorting people and businesses, and are often involved in stalking girls and peddling drugs, alleged locals of Savar's Dakkhin Para.
Savar residents yesterday formed a human chain at Muktirmore area, demanding immediate arrest of Mizan and his associates involved, and capital punishment for the culprits.
