The Rapid Action Battlion (Rab) arrested a man on charges of raping and killing a woman in Narsingdi’s Shibpur.
Police found the body of Sabina Akter, 21, at a banana orchard in Kazirchar village of the upazila on Saturday, two days after she went missing.
An autopsy at Narsingdi Sadar Hospital later revealed that she might have been raped after she was killed, police said.
A Rab team on Tuesday arrested suspect Saiful Islam, 28, in College Gate area of the upazila, said Lt Col Kazi Shamsher Uddin of Rab-11 at a press briefing at Narsingdi Press Club yesterday.
He added that Saiful told officers how he tried to rape the woman at an orchard on Thursday and killed her after she resisted his rape attempt.
Saiful, a father of two, strangled the woman with his shirt to stop her from screaming for help, interrogators said.
He then raped the corpse and left the scene with Sabina’s mobile phone and purse.
Rab officials also recovered Sabina’s phone, purse and Saiful’s shirt.
