Police recovered the body of Rafiqul Islam Rana, 24, from behind Metropolitan Hospital at around 11:45am.

The body had injury marks in the lips, head and neck with hands and legs tied with sweater and trousers, police said.

Miscreants strangled Rana, son of Awlad Hossain, sometime on Sunday night and dumped his body in a sewer, police suspect.

However, the reason behind the killing could not be known.

The victim's family identified the body the next day, police said.

"Rana left his Mohakhali residence at around 10:00pm on Sunday to drop his elder sister Rima Sayeed at her Nakhalpara house but did not return," said his brother-in-law Mohammad Panir.

Rana returned home from Malaysia last year and was trying to go there again, relatives said.

A case was lodged with Tejgaon Police Station.
