A human skeleton has been recovered from a makeshift wall at a six-storey building in the capital's Shewrapara area.
Primarily it was suspected that the bones were of a woman's body as a long hair was recovered with it.
A local plumber discovered the bones while repairing water supply lines at the flat, said police.
Some 150 bones, both whole and broken, were recovered one after another from the wall. Those were packed inside a polythene bag mixed with tea leaves.
Police have started investigating the incident since the horrific recovery was made on September 17.
Hanif Sarkar, the owner of the house who also has a furniture business, informed Mirpur police about the recovery. He was questioned by police.
The residents of the flat were terrified of the recovery. Of them, a school-going girl and women were the most affected from the incident.
Shyamol Khan, the person whose family now stays at the flat, yesterday said they rented the house in November last year. They were not allowed to leave the flat as police were still investigating the case.
The building owner said he started construction the establishment in 1990 and the work ended in 1993.
The building, holding No 389, was abandon for several months after the construction.
Prof. Selim Reza, head of forensic medicine at Shahheed Suhrawardi Medical College, said Mirpur police sent 156 pieces of bones for forensic test recently.
They have sent the samples -- teeth, bone and hair for DNA test. "It will take one to three months to get the result," he told The Daily Star.
Muntazirul Islam, officer-in-charge of Mirpur Model Police Station, said they were yet to get a breakthrough.
"From the building owner to tenants, everyone is a suspect to us in this case," he added.
