The girl has been identified as Liza, the daughter of Abdul Majid of Arankhola Union’s Gachabari village. She was a fifth-grade student of Gachabari Govt Primary School.
Her body was recovered from the orchard around 11pm on Friday, said Madhupur Police Inspector Md Nazrul Islam.
An initial investigation suggests she was strangled after she was raped, he said. Her body was taken to the hospital morgue for further examination.
Two suspects were grilled after receiving formal complaint, but their names could not be disclosed due to the ongoing investigation, he said.
Arankhola Union Council Chairman Abdur Rahim told bdnews24.com that Liza had been missing since Friday afternoon after leaving the house.
Her body was eventually spotted covered with banana leaves in a bamboo grove near her house. Her clothes were torn, he said.
